PURPOSE:To obtain stable AC output voltage from a DC/AC converter as an input of a transformer connected with a load to the output of two sets of transistors controlled in phase shift by the output of two sets of magnetic phase shifters by operating the phase shifters by a rectangular oscillator operated by a DC power supply. CONSTITUTION:Two sets of magnetic phase shifters 21, 22 are operated by the output of a rectangular wave oscillator 20 operated by a DC power supply 5. The control windings 212, 222 of the respective magnetic phase shifters 21, 22 are connecred in series with each other, control windings 213, 223 are also connected in series with each other, and a control circuit of the phase shifters 21, 22 is thus formed. Transistors 10, 12 controlled in phase through transistors 34, 37 by the outputs of the phase shifters 21, 22 are connected to two primary windings 14, 15 of the transformer 13 to allow the secondary winding 16 of the transformer 13 to produce an AC output. The output of the transformer 13 is also applied to the control winding of the magnetic phase shifter. |
