PURPOSE:To prevent the insufficient rotating speed of a load upon equalization of a load voltage to a power source voltage and the insufficient capacity of an air conditioner by providing a switch in parallel with a saturable reactor which suppresses the distortion in the wave form and the high frequency component. CONSTITUTION:A controller for an air conditioner has a DC power source 21, a reactor 25, a power transistor circuit 27 and a load voltage regulator 32. A switch 14' is provided in parallel with reactors 26, 26' in the reactor 25. This switch 14' is internally contained in a variable resistor 14 in the load voltage regulator 32. When a variable resistor 14 is rotated at the maximum voltage generating time, the switch 14' is shortcircuited, and the load 3 can be rotated substantially at the synchronizing speed. |
