Abstract

PURPOSE:To largely reduce inverter capacity, by incorporating the driving circuits in an auxiliary inverter section in a master and slave configuration into the main control circuit in a main inverter section. CONSTITUTION:The composition of the main circuit in an inverter 1 consists of a rectifier 2, a main inverter 3, and an auxiliary inverter 4 and the driving circuits in the auxiliary inverter 4 in a master and slave configuration is connected to the main control circuit in the main inverter 3. Therefore, the auxiliary inverter 4 works up to the predetermined number of turns and upon agreeing the frequency and phase of the auxiliary inverter 4 with those of the main inverter 3, Mg 51A-55A at the main inverter side are turned on and at the same time, Mg 51B-55B are turned off to perform the changeover for controlling motors 61-65.
