Recently, I saw a design reference on ti's official website. It uses a phase-shifted full-bridge solution, but the voltage transformer does not add a DC blocking capacitor. Why is it?

I asked before. Some people said that the current mode can be omitted. With automatic volt-second balance, the voltage mode cannot be used. Is that true?

You don't need to add it, but your CPU main program must have a program to filter out the DC component.

Adding a blocking capacitor can reduce the loss of duty cycle! But at the same time increase the voltage stress of the secondary rectifier diode..
