Title: COMPRESSOR CONTROL CIRCUIT, COMPRESSION APPARATUS, AND VEHICLE
Abstract:
A compressor control circuit (11) is provided with: an insulation-type DC-DC converter (50); an inverter control circuit (104); and a circuit board (100). In the insulation-type DC-DC converter (50), a primary side circuit and a secondary side circuit are insulated. The circuit board (100) is provided with a ground pattern wiring which is independent from a ground pattern wiring for a low voltage power source (60) system to which the primary side circuit is connected, and from a ground pattern wiring for a high-voltage power source (40) system to which the inverter control circuit (104) is connected, wherein a secondary side circuit, which is connected to the ground pattern wiring for the high-voltage power source (40) system only at one portion on the circuit board, is connected.
