All,
I am working on 2-phase interleaved bidirectional dc-dc converter as shown in the circuit below. I have not been able to find answers to the following questions running through my mind. The questions are:
1. How do I generate two independent PWMs of 180 degrees out of phase with dead time? In this case considering 50 kHz switching frequency and 50% duty cycle.
2. Which PWM generator can suite my specifications-PIC microcontroller, IC or 555 timers? I have PIC16F88 in the lab, can it do the job?
3. What is the best switching technique I can use for my design? I am using IR2101 as my gate driver.
Mate, please assist me on this; I am new on converter design.
Many thanks,
