Resonance Analysis and Soft Switching Design of Isolated Boost Converter
Apoorva [33] | Sangamesh Sakri [2]
Abstract: The resonance analysis and soft switching design of boost converter with coupled inductors is studied here. The resonance participated by voltage doubler capacitor, clamping capacitor and leakage inductance of coupled inductors, the problem of reverse recovery of secondary diode has been restrained within range of whole operation. By selecting suitable magnetic inductance of coupled inductors, ZVS on of main MOSFETs has been obtained in the same working condition, without the help of any device in addition. For achieving soft switching and an optimal operational point, the duty ratio range has been enlarged with minimum ripple current input, when duty ratio is approaching 0.5. Then for achieving power density, there are two types of resonances which are analyzed and also the optimized resonance has been used. The prototype is implemented for the vehicle inverter requiring 150w output power, input voltage range varying from 10.8 to 16v, and 360v output voltage.
