SMPS HB PFC SMPS TENAGA DAN KETAHANAN LUAR BIASA

This time I received an SMS service from our friend in Jogja. This SMPS was previously damaged and repaired in several places, but I was less fortunate and failed to work normally. In fact, the user said that there have been many MOSFET victims. Every time the MOSFET is installed it always shorts out when turned on. So that's the history of this SMPS until it reached me. This SMPS has a HALFBRIDGE PFC topology with the use of MOSFETs in parallel, so therein lies the complexity of this SMPS. Karrma, every time four SMPS MOSFETs are installed, they are always protected. The second difficulty was that I had to tidy up the condition of the components that had been installed but were not in a neat condition and looked like they were covered in service marks. So in the end I reassembled all the components and set the settings and the SMPS was working again well. #SMPSHBPFC
