1 Electrical description

This chapter provides an overview of the key features, specifications and pin assignments as well as mechanical dimensions.

1.1 Key features

The section describes the features of the evaluation PCBs and their key parameter. The Evaluation Board "EVAL-1EDI20H12AH-SIC" is intended to evaluate the Infineon EiceDRIVER™ 1EDC20H12AH or 1EDI20H12AH together with the Infineon SiC MOSFET IMZ120R045M1 in an application circuit to understand the features and performance of both devices. The board contains two gate drivers to drive two SiC MOSFET switches in half bridge configuration. An additional gate driver is used to transfer the over-current information through the isolation barrier between the power high voltage side to the low voltage input side. Some supporting circuits like voltage regulator and DC-DC converter are implemented for a simple use in the laboratory. The DC-DC converter provides galvanically isolated supply voltages for each SiC MOS driver stage. The picture shows the top view of the EVAL-1EDI20H12AH-SIC. Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiC™ MOSFET IMZ120R045M1 2 1.0 2017-11-30

Figure 1 EVAL-1EDI20H12AH-SIC top view The board has a size of 85 x 55 x 30 mm3. It is intended to be used for so called double pulse testing. However, it's under the responsibility of the user to adapt it for testing it under continuous operation by adding a heat sink. An additional blocking capacitor to the high voltage supply is recommended. The low voltage interface can be controlled by a pulse generator, a microcontroller or other digital circuits. For safe operation a fast overcurrent detection and protection circuit is implemented with a galvanically isolated feedback path to the low voltage input side. The trigger flip-flop is implemented to latch the overcurrent event information. This circuit will report the overcurrent event and turns OFF both drivers after an overcurrent event. The button S1 will reset the flip-flop to enable the drivers again. Further description is provided in the section Overcurrent protection.

1.2 Electrical features

1.2.1 Supply voltage, operating conditions and absolute maximum rating

The evaluation board is intended to be used in the laboratory for so called double pulse tests with limited power dissipation. The user has to ensure a stable supply voltage by adding an adequate capacitor. In case of continuous operation, the user has to take care of the cooling of the CoolSiC™ MOSFET IZM120R045M1 by adding adequate heatsinks. The heatsinks should be isolated from each other by using a separate heatsink for each transistor. The heatsinks should have a safe distance to the capacitors C5 and C13 to avoid arching due to high voltage.

1.2.2 Start up

To start the operation these steps have to be done: 1. Supply +15V at connector J4.1 with +16 V and connect supply GND to connector J4.2 2. The red LED4 will turn ON 3. Push S1 to reset the error flip-flop 4. The red LED4 will turn OFF and yellow LED3 will turn ON 5. Connect the digital driving device to the digital interface connector, labeled CON1:

• pin 6 for IN_T
• pin 8 for IN_B capacitor > 100 µF from J1.1 to J3.2 helps to stabilize the supply voltage. 7. Connect the inductive load to J2.1. The other side of the load can be connected to different nodes depending on the requirements. Please see Table 4 8. The board is now ready for tests Table 4 Load connection To be tested Connection 1st side of load Connection 2nd side of load Note High side driver TOP J2.1 J3.1 and J3.2 High side operation Low side driver BOTTOM J2.1 J1.1 or J1.2 Low side operation High- and Low side drive J2.1 J2.2 or another gate driver board Half or full bridge operation ENABLE must be pulled down to Low to enable a driver. The different drivers can be turned ON or OFF by driving either IN_T for the High side TOP or IN_B for the Low side BOTTOM driver at the digital interface connector. Only one input signal, either IN_T OR IN_B should be pulled to "High" to avoid turning ON both drivers at the same time. To adapt the circuit to the application requirements, resistor or capacitor values can be changed to optimize the performance.

1.2.3 Overcurrent protection

An over current protection is implemented to protect the board and components against high current . Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiC™ MOSFET IMZ120R045M1 5 1.0 2017-11-30

The current is determined by measuring the voltage across the shunt resistor R18. This is available at the two test points TP7 and TP10. The detection circuit measures the voltage across R18, sends the signal through a low pass filter R17 and C21 and compares it to a reference voltage with the comparator IC5. The reference voltage is defined by the voltage divider R11 and R19. The trip point is about 32A and can be adapted to customer requirements by changing R18 and/or adapting the reference voltage divider R11 and R19. The output signal is transferred with IC3 to the low voltage domain to trigger the flip-flop and store the over current event. Once the flip-flop is triggered, it turns off both gate drivers by the ENABLE signal. In addition, it reports the over current event to the digital interface connector as FAUL T signal and will turn ON the LED4. To go back to normal operation, S1 needs to be pushed to reset the flip-flop. As feedback, LED4 will turn OFF and LED3 will turn ON. The turn OFF of both drivers due to over current is displayed in the fig. OC T urn OFF and details in fig. OC T urn OFF details. The low side driver with load from switching node to HV supply was used to demonstrate the protection behavior. The HV supply voltage during the test was 530 V. The typical over current turn OFF threshold is about 32 A.

The Low voltage domain is shown on the left hand side and on the right hand side of Figure 4. It's typically used to connect to a microcontroller and supplied with VCC1. Every supply pin VCC1 has a blocking capacitor C8 and C18 to GND1. Every gate driver has two inputs:

• IN+, non inverted input, high signal will turn the corresponding SiC MOSFET ON.
• IN-, inverted input, high signal will turn the corresponding SiC MOSFET OFF. The circuit part on the right hand side of the schematic is the feedback interface to deliver over current signal information to the microcontroller. C2 and C5 are high voltage supply blocking caps. Only C5 is populated, while C2 is optional. J1 is the input connector for the high voltage supply. The connector J2.1 is connected to the center of the half bridge called PHASE. J2.2 is connected to the blocking capacitors C5,C13. C12 and C13 are high voltage supply blocking caps. Only C13 is populated, while C12 is optional. J3.2 is the connector for the high voltage supply ground. J3.1 is the connector to the shunt resistor R18.

2.1.1 High side gate driver TOP

In the top center section the high side driver, called TOP , is shown. It's the output of the gate driver IC2, supplied with VCC2_T and VEE2_T. VCC2_T is decoupled by the blocking capacitor C9 and VEE2_T has the blocking capacitor C10. The charging current of the SiC MOSFET T1 is limited by R3. The discharging current of the SiC MOSFET T1 is limited by R5. The capacitor C6 is optional and not populated. It can be used to decrease the switching time of T1 if needed.

2.1.2 Low side gate driver BOTTOM

In the lower center of the schematic the low side driver BOTTOM is shown. It's the output of the gate driver IC4, supplied with VCC2_B and VEE2_B. VCC2_B has the blocking capacitor C19 and VEE2_T has the blocking capacitor C20. The charging current of the SiC MOSFET T2 is limited by R10. The discharging current of the SiC MOSFET T2 is limited by R13. The capacitor C14 is optional and not populated. It can be used to decrease the switching time of T2 if needed. The shunt resistor R18 is used to detect over current. The low pass filter R17 and C21 will filter the voltage signal across R18 and deliver it to the comparator IC5. The reference signal for the comparator is created with the voltage divider R11 and R19 with filter capacitor C22. The over current detection threshold can be adjusted by changing the reference voltage with divider R11 and R19 or changing the shunt resistor R18. IC1 is a voltage regulator to create stabilized VCC2_5 out of VCC2_B. VCC2_5 is the supply voltage for IC5 and IC3. LED1 is a signal LED to show that VCC2_5 is available. C1, C3 and C4 are blocking capacitors for proper operation of IC1. IC3 is used as feedback part to transfer the over current information from the HV BOTTOM domain to the low voltage domain. The supply voltage VCC1 is supplied by VCC2_5 and blocked with the capacitor C15. The output side of IC3 is transferring from OUT+ and OUT- through R8 to the base of T6 of the fault flip-flip in the interface schematic. VCC2 of IC3 is supplied with +15V.

The interface schematic, in Figure 6, contains in the upper left corner the 5 V regulator IC6 to generate the VCC1 for the low voltage domain. The 10 pin interface connector to the digital driving circuit like a microcontroller, the 15 V input connector J4, the reset button S1 and VCC1 output J5 are placed on the lower left side of the schematic marked as connectors. The error flip-flop is displayed on the right hand side with the Status LED. It's triggered with the signal from R8 in the gate driver schematics. LED4 will indicate an over-current event and LED3 will indicate normal operation. The error flip-flop with over current detection circuit is intended to protect the board during lab evaluation. In the real application it's not required.

3 PCB Layout

A special PCB layout was developed to demonstrate the excellent performance of the components used. Main part is the interaction between the gate driver and the SiC MOS transistor as well as the current path for the high power supply, load and power GND. Also the supporting circuits like the DC-DC converter, the over current detection with the shunt resistor and the power supply of all circuit parts were optimized for this board.
