ABSTRACT:
An inventor system in which a first power supply system powers: a switching-element-group driving a motor, a charging-pump-type gate-driving-circuit, an inverter controller. A second power supply system powers an air conditioning controller outside of the inverter. An insulating communication circuit provides communication between the inverter controller and the air conditioning controller insulating these two controller. Most parts of the inverter system are powered by a single power supply system, i.e. the first power supply system, whereby electromagnetic noises are reduced, spaces involved in insulation can be saved, and the amount of wiring as well as cost is reduced.
