Abstract
One of a plurality of voltages is adapted to be applied to power supply terminals (). A rectifying circuit () rectifies the applied voltage and develops a rectified voltage between the output terminals () thereof. Inverters () are connected into one of a plurality of inverter connections between the rectifier output terminals () in response to one of a plurality of inverter connection indicative signals. The inverter connections are set to correspond to respective ones of the plurality of voltages, so that a predetermined voltage can be applied to each inverter whichever one of the plurality of voltages is applied to the power supply terminals. An inverter connection indicative signal generating circuit () is manually operated to generate a desired one of the inverter connection indicative signals. A thyristor () is disposed between the rectifier output terminals () and the inverters (). When one of the plurality of voltages is applied to the power supply terminals, a voltage detecting circuit () generates an inverter connection indicative signal corresponding to the voltage applied to the power supply terminals. A judging unit () determines whether or not the inverter connection indicative signals from the voltage detecting circuit () and the inverter connection indicative signal generating circuit () match. When the two signals match, a thyristor control unit () provides a CLOSE signal to the thyristor (). When the two signals do not match, an alarm circuit () is activated.
