<P>PROBLEM TO BE SOLVED: To stably supply a high output in a high-frequency band in an induction heating. <P>SOLUTION: A high-frequency power supply is structured by including: a DC power supply; two sets of primary winding of a transformer respectively connected to the positive and negative electrodes of the DC power supply; a set of secondary winding of the transformer actuated together with two sets of primary winding of the transformer to generate a synthesized high-frequency output; first and second thyristors respectively connected in series between two sets of primary winding of the transformer; and a lot of halfwave bridge-type oscillators constituted of a first and a second capacitors with their middle point in series connection connected to that of the first and the second thyristors, while they are connected in series to each other between the positive and negative electrodes of the DC power supply. <P>COPYRIGHT: (C)2009,JPO&INPIT |
