Abstract :
This paper designs a kind of BLDC sensor less control system for vehicle fuel pump. The control system uses 78F9222 of NEC as a core control unit, and uses the Back-EMF method to achieve the sensor less control for BLDC. The system can implement over-current protection, over voltage protection and over temperature protection. Loading test shows that the control system has high performance to meet the actual needs.
