Dear Team,
I'm working in a project, in which my customer requires AC power of 22kW, and frequency of the AC shall vary from 1kHz to 4kHz. For this i made current and voltage-controlled DC to DC converter, followed by an open loop inverter. Both converters are switched at 50kHz and Im able to make 1kHz to 4kHz AC using sinusoidal PWM. All are fine upto this. But problem is, the customer strictly saying inverter shall be operate in open loop mode, and they are giving this modulating pulses to the inverter. Because they should need the authority over sine frequency and amplitude of the AC output. Currently i tested this with the pulses from F28379d but moving towards customer side they will give this spwm pulses. but will not have better dead band. Currently Im planning to take these pulses to xilinx CPLD to give proper dead band. but that is making another complexity in the circuit/Hardware. Is there any way to give dead band to these pulses with F28379D itself ?
