发明名称	RESONANCE-TYPE SWITCHING POWER SUPPLY
摘要	PROBLEM TO BE SOLVED: To consistently reduce a switching loss by producing optimum resonance conditions. SOLUTION: A resonance condition changeover circuit 19 changes a resonance frequency according to a control signal supplied by a set 100 driven by a resonance-type switching power supply device 10 so as to make the switching power supply device 10 operate under optimum resonance conditions, according to the operational state of the set 100.
