Currently I am working on a battery charger for electric 2 wheeler.
The charger is an off board charger (kept outside the vehicle while charging).
Power rating is roughly 720 W i.e. 60V ,12 A
The dc-dc section of the battery charger is LLC HB converter with secondary side synchronous rectification. It is a digitally controlled by a c2000 processor. I am using INA180A4IDBVR for output current sensing through a shunt. Kindly let me know how to implement short circuit protection in this product. I have read about following methods that can be implemented digitally.
1) Increase the operating switching frequency beyond the resonant frequency.
2) Limit the duty cycle under 10 percent .
3) Disconnect the charger from the mains .
Is there any method apart from the above that can be implemented
