Abstract

A circuit board for power conversion 1 is a board mounting a power conversion circuit that converts a DC into an AC. On the circuit board for power conversion, a low-voltage circuit to which a low voltage is applied and a high-voltage circuit to which a high voltage is applied are arranged in different areas on the same board surface, respectively. In addition, with respect to the high-voltage circuit 10a, some wiring is formed on the board surface, and the other wiring is configured by a bus bar provided separately from the board surface by a predetermined distance.

Description

[0001] This application is a divisional application of the following patent application: [0002] Application number: 201680017453.2 [0003] Application date: February 15, 2016 [0004] Title of invention: Circuit board for power conversion and electric compressor technical field [0005] The invention relates to a circuit substrate for power conversion and an electric compressor. [0006] 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 [0007] 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 ...
