Editor’s note: There is a great deal written about isolation, but Frederik Dostal gives us a look at power supply isolation. Do you know which side of the galvanic isolation to put the controller?

This application note presents design guidelines for flyback converter using variable off-time controller-HFC0300 from MPS as shown in the figure. HFC0300 is a variable off-time controller which is ...

A medical system employs a 1-kW, four-phase, interleaved single-stage PFC circuit that provides a regulated 150-V dc from a single-phase 115-V ac, 60-Hz power source. This regulator serves as the ...

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or no ...
