Abstract
A plurality of half-wave bridge type oscillators are operated in a time-sharing method and connected through primary windings of a transformer to make the reverse bias hold time of each thyristor long. Therefore, it is possible to stably output a frequency and power which are several times as high as those in a conventional power supply.
Claims6
A high-frequency power supply comprising:
- a direct current (DC) voltage source;
- a transformer having two primary windings connected respectively to an anode and cathode of the DC voltage source and a secondary winding cooperating with the two primary windings for providing a high-frequency output;
- and
- a plurality of half-wave bridge type oscillators, each comprising first and second thyristors which are connected in series between the two primary windings of the transformer, and first and second capacitors which are connected in series between the anode and cathode of the DC voltage source and having an intermediate connection point connected to an intermediate connection point of the first and second thyristors.
