TIDA-00961: ZCD/ZVS detection function

Part Number: TIDA-00961

Hi Sali,

From the TIDA-00961 SCH, there's ZCD circuit and it also shows ZVS detection with the active_PWM signal, can you help to explain how it works?

1. What's the signal of the active_PWM signal?

2. It shows ZCD_output signal, but why it also states ZVS?

Many thanks.
