Abstract: PURPOSE: A boost converter of a soft switching mode is provided to improve power conversion efficiency by offering switching loss of a main switch through resonance of leakage inductance of a capacitor and a transformer. CONSTITUTION: An anode of a second circulating diode(116) is connected to a terminal between a main switch and an inductor for resonance. A cathode of the second circulating diode is connected to one end of the capacitor for resonance. One end of an auxiliary switch(117) is connected to a terminal between the second circulating diode and the capacitor for resonance. A primary side of a transformer(118) is connected to the other end of the auxiliary switch and a minus terminal of an input power source. A secondary side of the transformer is connected to an output terminal and a plus terminal of the input power source.
