PURPOSE:To arbitrarily control the power amount of a load coil operated in a parallel circuit with another power supply circuit by varying the current standard signal of a transformerless power supply circuit directly coupled with one generator and a plurality of rectifiers positive or negative. CONSTITUTION:The operation of rectifiers 3, 3' is arbitrarily controlled by forming the internal winding of a generator 4 in multi-layer winding to enable switching of terminal 8 in series or parallel and varying the current standard signal of a transformerless power supply circuit positive or negative. Thus, transformer and transformer shorting switches are omitted by positively ultilizing the winding of the generator to thus use low voltage rectifier as it is so as to thereby control the power amount of a load coil 5 operated in parallel circuit with another power supply circuit in a simple construction. |
