Title:
RESTRAINT FOR CHARGE CURRENT TO CAPACITOR
Document Type and Number:
Japanese Patent JPH0759358
Kind Code:
A
Abstract:
PURPOSE: To provide an inverter device which is simple in circuit constitution and economical and capable of downsizing.
CONSTITUTION: A maximum of charge current is limited, and the capacity of a DC reactor is made shall, and the disconnection at stoppage becomes possible by providing a solenoid switch 2, a DC reactor 3, and a diode 4 between a DC power source 1 and a smoothing capacitor 5, and feeding pulses being made by intermitting the solenoid switch 2 in short times. Hereby, the downsizing and the economization of the inverter device become possible.
