4.4 Current measurement shift stage and overcurrent threshold

Figure 8 shows the details of the current measurement shift stage. Figure 8 Current measurement shift stage In a single-shunt configuration, resistor RS1 is purposed to generate a voltage proportional to the sum of the source currents of the low side power IGBTs. This voltage is shifted using the shift stage shown in Figure 8 and is measured at pin ISS. The shift stage is made of a voltage divider and a low pass filter . Using the superposition theorem, it is possible to calculate the input current scaling and the shift stage offset. The input current scaling can be calculated using the following formula: 𝐼𝑛𝑝𝑢𝑡 𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝑆𝑐𝑎𝑙𝑖𝑛𝑔 = 𝑅𝑆1 𝑅16 𝑅16 + 𝑅17 𝑉/𝐴 The ADC dynamic range can be calculated using the following formula: 𝐴𝐷𝐶 𝑟𝑎𝑛𝑔𝑒 = 𝐼𝑛𝑝𝑢𝑡 𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝑆𝑐𝑎𝑙𝑖𝑛𝑔 3.3 𝑉 × 𝐼𝑛𝑡𝑒𝑟𝑛𝑎𝑙 𝐺𝑎𝑖𝑛 × (212 − 1) 𝑐𝑜𝑢𝑛𝑡𝑠/𝐴 Internal gain can be set via the iMOTION™ Solution Designer and the default value for REF-MHA50WIMI111T is equal to 3. Particular attention has to be paid when setting the internal gain to avoid saturating the ADC; it can cause a continuous GateKill fault status. The shift stage offset can be calculated using the following formula: 𝑆ℎ𝑖𝑓𝑡 𝑆𝑡𝑎𝑔𝑒 𝑂𝑓𝑓𝑠𝑒𝑡 = 𝑅17 𝑅16 + 𝑅17 × 3.3 𝑉 The overcurrent comparator reference voltage can be calculate using the following formula: 𝑂𝑉𝐶 𝑇ℎ𝑟𝑒𝑠ℎ𝑜𝑙𝑑 = (𝐼𝑀𝐴𝑋 𝑝𝑒𝑎𝑘 × 𝐼𝑛𝑝𝑢𝑡 𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝑆𝑐𝑎𝑙𝑖𝑛𝑔 + 𝑆ℎ𝑖𝑓𝑡 𝑆𝑡𝑎𝑔𝑒 𝑂𝑓𝑓𝑒𝑠𝑡) 𝑉

5 Thermal characterization

Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , and Figure 14 show the thermal characterizations o f the reference board. The tests were performed under the following conditions: Tamb = 25°C, input voltage VDC = 300 V, two different PWM modulation types (3-phase PWM modulation and 2-phase PWM flat bottom modulation). Figure 9, Figure 10, Figure 11, and Figure 12 show results of tests performed under two PWM frequencies (6 kHz and 16 kHz) and different motor phase current values or different input power s. Figure 13 and Figure 14 show results of tests performed under diffe rent PWM frequencies (4 kHz to 20 kHz) till Tcase = 100°C was reached . A 2-phase PWM flat bottom modulation enabled the reduction in switching losses compared to a 3-phase SVPWM (symmetrical placement of zero vectors).

5.2 Thermal PCB design

IMI111T relies on the leads to transfer thermal dissipation from the power devices to the PCB. There are several critical pins that need attention to achieve improved thermal performance of the module. Figure 16 shows the pins critical for thermal dissipation. These include V+ (17, 18), UN (12), VN (13), and W (14, 15). Copper areas connected to the critical pins have to be optimized as much as possible to provide more thermal transfer capability, and this is especially important for single layer PCB design. In this reference design, the motor connector J3 is placed very close to the critical pins UN and VN, and it helps acting like an external heatsink to extract the heat more effectively. Figure 17 shows the PCB design with respect to the critical pins. Module

6 Thermal protection

The IMI111T devices feature an integrated temperature sensor that helps in monitoring the internal temperature of the module. The device temperature can be accessed using script engine language. The particular register name for this functionality is “InternalDieTemp [2]” in iMOTION™ Solution Designer dashboard variables list and the register value is in Kelvin [K]. To enable overtemperature protection for the REF-MHA50WIMI111T starter kit, a corresponding script file (.mgs) has been pre -loaded into the IMI111T mounted on the REF-MHA50WIMI111T starter kit, along with the latest IMI111T software package and parameters. To activate the overtemperature protection, the script project needs to be set up, built, an d programmed in iMOTION™ Solution Designer script editor window during system setup. Please refer to the application note How to use iMOTION™ Script Languag e [2][3]for more details about the iMOTION™ script functionality. Chapter 7 of this user guide provides the operative method for script application. The script that is used for overtemperature protection in REF-MHA50WIMI111T is shown in Code Listing 1, Code Listing 2 and Code Listing 3. The script has been implemented to stop the motor when the sensed temperature reaches 101°C (shutdown temperature) and to restart the motor when the sensed temperature goes below 60°C (restart temperature). Please note that the sensed temperature is the controller temperature, whereas , overtemperature is generally triggered by the case temperature of the module. Based on experimental results, Figure 18 shows the relationship between the case temperature and the internal sense temperature. Customers can use this curve to determine their internal sense temperature for thermal shutdown.
