Power converting apparatus and filter switch

摘要

A power converting apparatus includes a switching element, a filter substrate, a housing, a main body, an air duct, and a filter switch. The switching element is configured to convert and output power. The filter substrate includes a filter circuit configured to reduce transmission of noise generated in the switching element to an input power source. The housing includes a housing base having a first surface and a second surface. The main body is on the first surface of the housing base, and includes the filter substrate and a plurality of electronic components. The air duct is disposed on the second surface of the housing base, and cooling air flows through the air duct. The filter switch is on the first surface of the housing base. The filter switch is configured to switch between making and breaking electrical conduction between the filter circuit and the housing.

1. A power converting apparatus comprising:
a switching element configured to convert and output power; at least one filter substrate comprising a filter circuit configured to reduce transmission of noise generated in the switching element to an input power source; a housing comprising a housing base having a first surface and a second surface; a main body on the first surface of the housing base, the main body comprising the at least one filter substrate and a plurality of electronic components; an air duct through which cooling air flows on the second surface of the housing base; and at least one filter switch comprising a switch main body and a screw, the switch main body including at least two first insertion holes and at least one second insertion hole each being configured to receive the screw, wherein the at least one filter switch provides electrical conduction between the filter circuit and the housing when the screw is inserted within either of the at least two first insertion holes of the switch main body, and wherein the at least one filter switch does not provide electrical conduction between the filter circuit and the housing when the screw is inserted within the at least one second insertion hole of the switch main body.
