Typical applications are motor control, brightness control, temperature control, cos optimization for squirrel-cage motors, and starting current limitation. Thanks to their high efficiency, the TLE 310 xICs are particularly suitable for consumer goods, such as kitchen appliances and washing machines, vacuum cleaners, electric irons and hobbyist appliances.

-eeoOoO NANA TLE 3103 TLE 3104 Functional Description The following is a description of the individual functional units (refer to block diagram) and their interactions: Operational Amplifier op amp ‘Two inputs and the output are available. The op amp is internally compensated and has a push-pull output. Should the op amp not be required, the +input must be connected to ground (the TLE 3101 and TLE 3102 then consume minimum current). Comparator K 3 Comparator K3 is not frequency-compensated. The output is an open NPN collector which in switching operation may drive an LED, for example. Should the comparator not be required, the —input must be connected to ground. K3 then has minimum currentconsumption E Reference Voltage Source A temperature-stabilized voltage source is available for control and regulating circuits. Sawtooth Generator In this unit, a sawtooth synchronized to the line is generated by the external Rg and Cs The phase angle of the triac is determined by comparison of the sawtooth voltage and the control voltage. The trigger pulse width for the driver is provided by the falling edge of the sawtooth generator. The charge of Cs determines the trigger pulse width. A special circuit ensures the release of only one trigger pulse per line half period Comparators K1, K2 Sawtooth voltage and control voltage are compared by means of comparators K1 and K2 Comparator K2 receives only half the sawtooth voltage. The phase angle limit can be adjusted within the complete phase angle range by applying a reduced reference voltage to input “Vmax”. Comparator K2 provides starting current limitation and/or phase angle limitation for inductive loads. Both comparator outputs are fed to the logic and driver unit. The comparator with the smaller conduction angle is the dominating one. With Vemax dominating, the trigger pulse width is doubled - compared with the trigger pulse width in case of a dominating Veontrol Logic + Driver The logic and driver unit for triac triggering is controlled by comparators K1, K2, and the enable input E/A. The E/A input is TTL-compatible and may disable or enable the trigger pulse. Logic +driver obtain information on the trigger pulse width from the sawtooth. The undervoltage monitoring enables the driver output only if the IC’s supply voltage has reached the permissible minimum value. The driver output to the triac supplies negative pulses Siemens Aktiengeselischaft 325
‘Synchronization At the sync input, the phase angle is synchronized to the zero crossing point of the line voltage. The sync pulse width tT sync has to be twice as large as the trigger pulse width.

Calculate Cg (for a Veoniro1 domination) Cz (nF) = trigger pulse width (us) x 0.2 The formula yields the typical value e.g. T= 50 ps results in Cs = 10 nF 3. Calculate Rg (for 4 V max. sawtooth voltage) trigger pulse width (us) The formula yields the typical value e.g. T=50 ys results in Rs = 400 kQ 4. Select Rsynic resistance at SYNC input The sync pulse width (from Vs + 7.5 V, Isync = + 20 pA) has to be twice as large as the trigger pulse width.

Current Synchronization in Case of Inductive Load Control Using TLE 3104 Particularly in case of phase control of inductive loads, such as transformers and shaded- pole motors, there is a risk of half-wave operation as a result of the phase shift between voltage and current. In order to avoid this condition, the synchronization resistor is con- nected to A 2 of the triac (this method cannot be applied in the event of severe brush sparking of the motor). a . Mien : Li | | ‘ne ene ra 4 cs Hees | fr 7 > le | 7 , vwonof] 220r ! —— —— AS ERK sweeos 0, 7 — i g . ; Notes The pulse width selected for the trigger pulse must be so great that the triac reaches its holding current, even with a great phase angle (critical: positive half-wave). For this reason, it may be necessary to select a lower value for the ac line series resistor. The sync pulse must be at least twice as wide as the trigger pulse. Siemens Aktiengesellschaft 336
