Tool/software:
Hello everyone,
I would like to inquire about the solution to a certain problem. I'm developing the Totem Pole PFC circuit. I'm using DPWM1 to control the switching transistors. During the positive half-cycle of the AC input, B serves as the main switch transistor while A acts as the synchronous switch transistor. So, how can I make the high-level time of A equal to the switching period minus the dead time minus the DUTY (the output of the CLA)?
I intended to implement this function by using D_ENABLE, but it can only achieve the switching cycle - DUTY(the output of the CLA). The dead zone time cannot be subtracted.
Thank you sincerely for your help.
