Inverter controlling apparatus for driving motor

摘要

By reducing the variation value of a motor current, an inverter controlling apparatus for driving a motor having a small size and a light weight may be implemented in low cost employing a small inductance reactor and a small capacitance capacitor. The operation of the motor can be maintained by maintaining a substantially constant voltage applied to the motor by the PN voltage correcting means, even for the case that the motor is difficult to be operated owing to a variation of the inverter DC voltage in a large scale. Accordingly, by reducing the varying amount of the motor, the inverter controlling apparatus for driving the motor and the air harmonizer using same which achieves the small size, light mass can be provided in low cost. <IMAGE>
