Power conversion circuit board, and electric compressor

Abstract

This power conversion circuit board (1) has a power conversion circuit mounted thereon for converting direct current to alternating current, and comprises a low voltage circuit, to which a low voltageis applied, and a high-voltage circuit (10a), to which a high voltage is applied, separated into different areas on the same board surface. Further, the high-voltage circuit (10a) is configured froma busbar, with part of the wiring thereof formed on the board surface, and the other part of said wiring separated by a prescribed distance from the board surface.

Description

technical field [0001] The invention relates to a circuit substrate for power conversion and an electric compressor. [0002] This application claims priority to Patent Application No. 2015-060840 filed in Japan on March 24, 2015, and uses the contents thereof here. Background technique [0003] For example, because it is necessary to accommodate various structural equipment in a limited space in a vehicle, a high space-saving property is required for a vehicle-mounted air conditioner. Therefore, in recent years, for the purpose of improving space saving, an integrated electric compressor (for example, refer to Patent Documents 1 and 2) is provided. A motor for driving the compressor and a circuit board for controlling the compressor are integrally formed. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2008-099480 [0007] Patent Document 2: Japanese Patent Application Laid-Open No. 2011-2293...
