    four switch inverter as driver for three phase induction motor

    have u ever do a c block in psim that contain codes switching sequence for output 3 phase from the input 1 phase? i think the mistake i made in coding input.

    four switch inverter as driver for three phase induction motor

    The root of the problem is when I start the simulation using PSIM with 4 IGBTs and 2 capacitors, it doesn't produce a balanced current output. Here, I need to learn about the oscillator circuit used to control these IGBTs. Do you have any suggestions? Thank you.

    four switch inverter as driver for three phase induction motor

    I have set up a system use 4 IGBTs for an inverter that will drive a 3 phase induction motor in a simulation using PSIM. The output of the 3 phase should use 6 IGBTs, but I'm using 4 IGBTs and connecting the other phase with 2 capacitors. However, the current from these 3 phases is unbalanced...
