This project is funded by Chong Qing Xian Feng company to develop a brushless DC motor (BLDCM) controller with regenerative brake system for light electric vehicle.
The key of this project is low cost and high reliability, so the minimum change of tradition controller’s circuit toplogy is important
In this project, a new current sensing method and control algrothm were used in the BLDC controller. About the detail please read my paper “Regenerative Brake of Brushless DC Motor for Light Electric Vehicle”.
