Application of a dc control current to the secondary winding varies the magnetic flux in the ferrite core, altering the inductance of the primary winding (114), thus changing the natural resonant frequency of the LC circuit. A Variable capacitance diode (102) is connected across the secondary ...
A Coupled-Inductor-Boost high voltage gain converter with a nondissipative LC snubber was presented. By utilizing a snubber circuit composed of capacitor, inductor and diode, leakage inductance energy was recycled and voltage spike stress of the power switch was suppressed. Compared with active c...
