hello sir,

i need a formula to choose the input capacitor for the half bridge with capacitor dc to dc converter. And in order to maintain equal potential across the capacitor,a resistor across each capacitor can be added. but how to calculate that resistor value.

thanks in advance.

Regards,

Manikandan
 

Hi Friend
It depends on your switching frequency , your current , your voltage , your ripple . or is your mean by the input capacitor , Bulk capacitor?

Pls find the image. And let me know how to calculate the capacitor value. If you gives me the formula,i will substitute the values u mentioned above and i will find the value.
Its a bulk input electrolytic cap.
