Power converting device for reducing induction trouble.

摘要

In a power converter, the inverter device casing (20) and a heat receiving plate (18a, 18b) are insulated, and the heat receiving plate (18a, 18b) and a filter capacitor (7) are connected through a predetermined inductance. Since higher-harmonic current is bypassed to the filter capacitor (7) through a resonance filter which is constructed of the electrostatic capacity in a switching element and an inductance, induction trouble, which might otherwise be caused by higher-harmonic current leaking to the outside of an inverter device, can be reduced by a simple construction.
