in power supply(half bridge switching) we use the tuning cap. to improve the primary current ,can someone help me how it is working and how we design it ,and some power supply use polarity cap. ,and we some times add resistor in parallel with the cap.
so please can someone help me to understand this

 

Hello Takymounir. What you are asking an explanation of isn't completely clear. It would be vastly helpful if you can provide example circuit diagrams and explain exactly which components (and functions) you are asking about.

Thanks.
