DC-Link DC-Link Busbar Plate with High Capacitance

摘要

The present invention relates to a DC-Link bus bar having a high capacitance, and in an inverter system having a high switching frequency, a DC-Link bus bar itself is designed to have a high capacitance, so that a snubber capacitor having a high parasitic inductance can be removed And it is an object of the present invention to provide a DC-Link bus bar having a high capacitance. To this end, the DC-Link bus bar having a high capacitance according to the present invention includes a (+) DC-Link bus bar portion for minimizing parasitic inductance, a (-) DC-Link bus bar portion for minimizing parasitic inductance, Wherein the insulating fins to be maximized are laminated to form a plate shape; A snubber unit for compensating the capacitance is formed on the outer side of the (+) DC-Link bus bar portion and the (-) DC-Link bus bar portion.
