The invention provides a compressor control device and a compressor vehicle, and the compressor control device comprises a high-voltage drive control circuit which comprises a high-voltage DC circuitfor providing high-voltage DC; the high-voltage power supply conversion circuit is connected with the high-voltage direct current circuit and converts the high-voltage direct current into power supplyvoltage of a load circuit and / or a load in the high-voltage driving control circuit; the compressor control device further comprises a low-voltage drive control circuit which is connected with the communication bus so as to exchange signals with the communication bus; and an isolation communication circuit which is electrically connected with the low-voltage drive control circuit and the high-voltage drive control circuit so as to realize signal exchange between the low-voltage drive control circuit and the high-voltage drive control circuit. The high-voltage power conversion circuit is arranged in the high-voltage drive control circuit, so that the effect of directly providing power supply voltage for the load circuit and / or the load in the high-voltage drive control circuit is achieved,and high standby power consumption of the low-voltage drive control circuit is avoided.
Description
technical field [0001] The invention relates to the field of electric vehicle compressors, in particular to a compressor control device, a compressor and a vehicle. Background technique [0002] The compressor used in the vehicle air-conditioning system usually adopts a three-in-one structure of mechanical parts, rotating motor, and controller. The controller drives the rotating motor to provide power for the compressor to circulate refrigeration. Conventional motor drive control technology mainly converts high-voltage direct current into three-phase alternating current through an inverter circuit, and controls the rotation of the motor by changing the amplitude and frequency of the three-phase alternating current through a microcontroller control algorithm. Usually, the microcontroller communicates with the upper computer of the vehicle system through an isolation device to realize data interaction. Vehicle systems usually sample high-speed communication buses such as CAN ...
