PROBLEM TO BE SOLVED: To realize a converter which is simple-structured and rerely has electromagnetic noise and has only a small switching loss. SOLUTION: In this converter 11, a switching device 12 connected to a primary winding of a high-frequency transformer 16 and a resonance capacitor 14 connected to both ends of the primary winding of the high-frequency transformer 16 or between the collector and emitter of the switching device 12 constitute a resonance inverter. The output of the inverter is transmitted to the high- frequency transformer 16 and then is waveform-shaped by a rectifier 17 and a frequency converting circuit 19, both of which are connected to a secondar winding of the high-frequency transformer 16. |
