Automatic air-conditioning compressor driver and controller

Year:
2008
Category:
Electric vehicle key technology
Technique Features:

This controller is aimed to drive the hybrid compressor to provide A/C to the vehicle with stop-and-go function. The driver provides the optimal control ability for the motor with the intelligent power management and control algorithm.

Specification:

1.Optimal motor control mechanism and intelligent power management algorithm
2.Motor control module: operating voltage 24V, maximum operating current 100A, PWM frequency 2MHz, current measurement 0~100A with tolerance 40mV/A, PWM Module, phase-change control and rotational speed calculation of the driven motor

Applications:

Hybrid compressor, electric compressor

Benefit:

The technology could provide proper operating conditions for the motor which could reduce the unnecessary power loss and the power consumption of the AC system.
