    Dead Time PWM Controllerl Circuit to drive a half bridge IGBT inverter

    The signal comes from the matlab, but it is a open loop ref signal, because due to my limited knowledge in control i wasn't able to design such controller. The open loop ref signal frm matlab is output from dSPACE and using a comparator circuit, i used a triangular carrier signal of 7 - 12khz...

    Dead Time PWM Controllerl Circuit to drive a half bridge IGBT inverter

    no i am using the International Rectifier IR2111, it is somewhat similar to what you have intro me just now for IR2183/IR2184. Just want to ask another question, because i am working on a single phase shunt active filter, can the IR21844/IR21834 withstand high power switching for the IGBT? Any...

    Dead Time PWM Controllerl Circuit to drive a half bridge IGBT inverter

    Is there any other way to increase the dead time to 1.5 to 2 microseconds. Currently i am using the IR2111 with 500ns time delay, but i am also unable to get to 500ns, i am also unsure y is it so?

    Dead Time PWM Controllerl Circuit to drive a half bridge IGBT inverter

    Good Day Everyone, May i check with you all, anyone knows how to design a dead time control circuit that can be used to provide two square wave signals to the half bridge IGBT inverter. It is the best that the two signals can have a dead time of 1.5 - 2 micro seconds. Please kindly assist...
