Abstract

PURPOSE: To simpliry the circuitry by obtaining 3-phase AC current having a frequency equivalent to 75% of the power supply freqency direct from the 3-phase AC power source.
CONSTITUTION: Arranged are 3-phase windings 5a∼5c for inducing current of the reference three phase and the first to third auxiliary windings 6a∼6c, 7a∼7c and 8a∼8c each made up of three windings adapted to separately induce current in a phase identical to the reference three phase and three phases lagged by 40° and advanced by 40° from the reference three phase. The first to third auxiliary windings 6a∼6c, 7a∼7c and 8a∼8c are connected in sequence to respective phases of the load 9 shifted by one cycle with respect to the phase angle of the 3-phase AC power sources 1∼3 with the first to third electric valves 10∼12, 13∼15 and 16∼ 18.
