pfc

Hello Everyone I have a question. I've repaired a Corsair HX1000 power supply (for myself to use as a spare) that I got from someone who chucked it away. The two main switching transistors failed as well as the PFC circuit. The issue is, the PFC circuit uses 3 × IPA50R140CP MOSFETs and the...

Hello all, I have been checking this 30 kW Vienna PFC rectifier reference design and didn't understand why all of these filters are used for this kind of application, i mean half of the board is inductors and capacitors for the filters. Can someone explain what type of filters are used? and...

I tried to understand PFC in an SMPS voltage converter. I read from many websites but still confused very much about the following things. Situation: it’s an SMPS flyback (for example) converter, to output (for example) 24v dc to an inductive load of 100W (average). Input 230v AC mains 50Hz...

I've been looking at UCC28C43 models provided by TI. Why do we need two different Spice models such as "Transient steady-state" & "transient start-up" for MOSFET driver IC? How do we use them? When do we need these analyses? Do all microcontrollers in power electronics have such separate models...
