Abstract

PURPOSE: To drive an inductive load in the maximum power factor at all times and to obtain an energy saving effect on a large scale, by instantaneously controlling the load voltage on the optimum level depending on the load condition.
CONSTITUTION: A load condition detection circuit 32 generates an output signal corresponding to the load condition of an inductive load 18 and controls the conduction ratio of a semiconductor switching circuit 30 with a control circuit 34 in response to its output signal. With this semiconductor switching circuit 30 the DC exciting current supplied to a control winding 26 is varied. By varying the DC exciting current of the control winding 26 in a voltage regulating three- phase autotransformer 24, the output voltage supplied from the voltage regulating autotransformer 24 to the inductive load 18 is variably regulated depending on the load condition.
