| Abstract: |
This paper aims to analyse the behaviour of a parallel quasi resonant converter for a proposed solar based induction cooking system under ZVS condition. The IGBT incorporated in the resonant converter will switch as a self-oscillating circuit and operate under ZVS condition to minimize switching losses. The resonant converter simulation design responds to different equivalent pan resistances and it can be said that the equivalent pan resistance of 5Ω will provide the maximum efficiency of the system at a resonant frequency of 20KHz. The resonant frequency can be varied by changing the duty cycle parameter in the control part of the design for a range of 14KHz ~ 33KHz. The output power of the cooking pan is seen to vary for different pan resistances to obtain an effciency of the system that varies within the range of 75% ~ 93%. The resonant converter was designed and analysed in PSIM software to show these analysis. |
