Title:
ELECTRIC COMPRESSOR CONTROL SYSTEM AND ELECTRIC COMPRESSOR FOR VEHICULAR AIR CONDITIONING DEVICE PROVIDED WITH SAID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/156063
Kind Code:
A1
Abstract:
The present invention mitigates electromagnetic noise that is generated from a substrate on which a microcomputer, etc., are mounted. In the present invention, an electric compressor control system has regions (10, 20, 30) divided by a plurality of ground patterns formed on a substrate (100). On the substrate (100), an information obtaining line (51) from a vehicle is formed so as to traverse the regions (10, 20, 30) divided by the plurality of ground patterns, and the information obtaining line (51) from the vehicle is connected to a microcomputer (70) provided on the substrate (100). A coil (41) is provided in a portion of the information obtaining line (51) from the vehicle at a location that traverses the region (10) and the region (20) divided by different ground patterns. The coil (41) reduces noise generated from the information obtaining line (51) from the vehicle.
