Abstract

PURPOSE:To prevent the commutation failure at the time of starting beforhand by connecting the output terminals of a current-type inverter to a load motor by way of a switching means which is closed after a specified period has elaspsed from the time of starting said current-type inverter. CONSTITUTION:Output terminals U, V and W of an inverter 4 are connected to a load motor 5 by way of a switching means, e.g. an electromagnetic switch 6. Said electromagnetic switch 6 is closed after a specified time from the start of the inverter 4. This can be implemented, e.g. by a timer which is actuated by a starting signal of the inverter.
