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.
Brian Zhao
Hi Brian,
Active PWM is the PWM output used for driving the switching FET in the half bridge (not the complementary signal used for driving the synchronous FET). The expected waveforms are as below. We never tested the functionality of the circuit though.
