A 1.5 kW two transistors forward converter using a non-dissipative snubber

This paper will present a 1.5 kW operation with 90% efficiency at full load of a two transistors forward converter with non-dissipative snubbers. The proposed approach allows building a converter with high frequency operation. A detailed analysis of the operation will be presented. The output voltag...

Zusammenfassung:This paper will present a 1.5 kW operation with 90% efficiency at full load of a two transistors forward converter with non-dissipative snubbers. The proposed approach allows building a converter with high frequency operation. A detailed analysis of the operation will be presented. The output voltage is controlled by PWM with a constant frequency. The complete operating principles, theoretical analysis, relevant equations, simulation and experimental results will be presented.
