TIDA-010062: zero detection of synchronous rectification

Jianing Zhu

Part Number: TIDA-010062

How to realize zero detection of synchronous rectification in TIDA-010062? it seems the SDK doesn't include this part.

Jianing,

The PWM state machine solve this issue.

The algorithm is in the ttplpfc.h. The function name is TTPLPFC_pwmDriver();

C2000 use AQ force function to control the low frequency MOS.

Hi Jianing

We haven't done ZCD for SR FET, and it is estimated it by resonant frequency.
