PURPOSE:To obtain a converter of high efficiency and high output even in high frequency, by a method wherein an oscillation circuit is connected to the first winding of a conversion transformer, and wherein phase control signal is received from the third winding and output is taken out of the third winding. CONSTITUTION:Power supply terminals 1, 2 are connected to an oscillation circuit 5 via gard circuit 3 and rectification circuit 5. The first winding 32 of the conversion transformer 6 with the third winding 34 is connected to the oscillation circuit 5, and the third winding 34 is connected to a phase control circuit 7, and the oscillation circuit 5 is combined with the phase control circuit 7. And the second winding 33 of the conversion transformer 6 is connected to the output ends 35, 36 and the output is arranged to be taken out. As a result, the loss of the oscillating transistor 29 can be reduced, and the collector voltage and temperature of the oscillating transistor can be corrected, and so the high efficiency and high output can be obtained. |
