hello sir, i was developed the DTC of induction motor its working fine in mat- lab simulink with dSPACE1104 i was observed the switching pulses in CRO but problem is when i was applied these pulses with DAC to IGBT inverter its. not triggered. please tell me the solution.

For urs question,better u try it out with dsPIC processor or in any other controller in order to generate the switching pulses to the inverter/converters

You should use PWM output pulses instant of DAC, then seperate IGBT gate driver and opto isolator circuits should be connected. then only IGBT will trigger.
