Abstract

PURPOSE: To raise the conversion frequency without raising the switching frequency by the method such that n primary windings are respectively electromagnetically connected to the secondary winding of a transformer, and further, a frequency voltage of n times the switching frequency is produced in the secondary winding by n switching circuits.
CONSTITUTION: No.1, NO.2 and No.3 primary windings N1, N2 and N3 are provided. To these is electromagnetically connected transformer secondary winding Ns. Ns is provided with output terminals 1, 2. In inverter circuit 3, which converts DC into AC, No.1, No.2 and No.3 switching circuits 4, 5 and 6 are connected between primary windings N1, N2 and N3 and DC power source 6. The polarity of the direction of current in three primary windings N1, N2 and N3 is changed, and an output frequency of three times the switching frequency of No.1, No.2 and No.3 switching circuits 4, 5 and 6 is obtained.
