In the circuit, a bridge like circuit comprised of igbt transistor is used which converts dc to ac. Separate provision for load section. A single phase inverter takes the dc voltage as input and converts it to single phase ac voltage while a three phase inverter converter converts the dc voltage into three phase ac voltage. 3 phase inverter circuit using igbt author:
Let’s assume that a 3‐phase, balanced (ra = rb = rc), resistive load is connected to terminals a, b, and c of the inverter (as shown on the previous page).
Let’s operate the inverter in the simplest way possible: Single phase inverter and three phase inverter. Alternatively, a three phase inverter uses two input dc sources, using 6 igbt transistors to convert dc voltage into ac voltage and the output of such a circuit will be a three phase ac waveform with a phase difference of 120. 3 phase 6 pulses, 12 pulses is optional.
