Abstract

PURPOSE: To stabilize switching work, by adding a control circuit anew to a reference sinusoidal wave generation circuit.
CONSTITUTION: The input section of the second PT 111 is connected to a preliminary output power source 105, whose output section is connected to an A/D converter 116 on one hand, and on the other it is connected to a reference sinusoidal wave generation circuit 113. The output of the A/D converter 116 is connected to the above-mentioned generation circuit 113 so as to be stored to an external memory 119 as a digital signal with a microprocessor unit 118 (MPU). On the other hand, the output voltage waveform on an inverter circuit side is inputted from an AC filter circuit 104 of an inverter device to the generation circuit 113 through the first PT 107. Eddy current will thereby be generated to the output current of the inverter device. When the preliminary output power source 105 becomes feeding condition, the voltage waveform is converted into a digital signal by the A/D converter 116 and is stored to the external memory 119. Then, this is converted into an analogue signal with the above-mentioned generation circuit 113 and is controlled so as to synchronize the output voltage phase.
