    I found a Demo in Simulink for Single Phase Inverter using Sine-PWM. I started to practice by building up a simple single phase inveter without PWM. I faced a problem in triggering the four IGBT switches in a Full bridge inverter. I tried to make IGBT1_2 and IGBT 2_4 to switch together and the other two do the same. I added pulse generator to each IGBT switch, but I am having a problem in setting up the parameters. I am not getting any output signal after useless attempts. Please Help..

    Find attached the circuit and Pulse generator parameters. I need to to knw the parameters for each IGBT pulse generator

    What voltage is the pulse generator output? Is it only 1 volt? That is probably not enough to turn the IGBT on. What is the V(GE(threshold)) for the parts you are simulating?

    sorry, I 4 got 2 change the 1 volt amplitude in the attachment. I am using 5 volts to trigger the IGBT. In the demo, 5 volts were used in the pwm operation which is enough to trigger the IGBT.
