This paper proposes an improved partially interleaved structure for high-voltage (Several kV) high-frequency (Several hundred kHz) multiple output applications. Six structures are compared with the leakage inductance, AC capacitance and the rate of AC/DC resistance taken into consideration. The proposed structure features lower leakage inductance, smaller AC capacitance and lower rate of AC-DC resistance,...
This paper proposes a novel LCLC full-bridge resonant converter with ZCS and ZVS for high-voltage high-frequency applications. In this operating model, both of ZCS and ZVS can be achieved and the switching losses can be reduced to a minimum. The proposed converter adopts the parasitic parameters of the step-up voltage transformer and one other serial capacitor is needed to form the resonant tank....
The magnetic shunt is generally inserted in a planar transformer to increase the leakage inductance which can be utilized as the series inductor in resonant circuits such as the LLC resonant converter. This paper presents a calculation methodology for the leakage inductance of the transformer with a magnetic shunt by means of the stored magnetic energy in the primary and secondary sides of the transformer...
