Abstract :
This paper presents an alternative of pulse width modulation flyboost converter to achieve a regulated high voltage high power direct current power supply. The proposed flyboost converter in this paper composed with a conventional boost converter and flyback converter, which generated energy from the boost inductor during an off time period. Thus the higher-gain converter can be achieved in the proposed flyboost converter by the summation of both output voltage, boost and flyback converter. The circuit configurations, basic principle operation, mathematics analysis, design consideration and testing results of the proposed high gain step-up flyboost converter were described in detail. Finally, the results of a 20-30V input, 100V 100W output switched at 150 kHz flyboost converter, which was designed in this paper, showed the effectiveness of the converter was 87.26% and 2.76% of voltage regulation respectively.
