Abstract

PURPOSE:To make it possible to realize the arbitrary load condition with good responsibility in equivalent by a method wherein the current that variable forward and backward flows from the variable direct current source to the direct current reactor is controlled by a PWM switching in accordance with the load current wave form reguired at the loaded source. CONSTITUTION:The arbitrary loaded source, for instance against the single phase alternating source 1, so as to the same way when the current ia is connected to the desired load ZL, the load system consists of a filter 2, a PWM switching control circuit 3, direct current reactor 4, a forward and backward variable direct current 5 is controlled to realize the equivalent loading condition. For example, in the case of the load current wave form iar of the linear condition load against the source voltage wave form ea of the sine wave is as indicated in the fig., the flows in the current wave form id is controlled by the PWM switching control circuit 3 consists of thyristors etc. S1-S4 when it is through the filter 2 is made to be the desired current wave form iar. Thus the arbitrary load condition can be realized with an excellent responsibility and efficiency.
