High-efficiency BLDC motor regenerative braking system with new single-switched transistor control algorithm

Year: 2025

Type: article

Abstract: • Regenerative braking system in an electric vehicle increases its range. • High-efficiency converter is essential for electric vehicle drives. • Reverse conduction of power field effect transistors reduces losses. • New brushless motor control algorithm increases drive efficiency. This paper presents a new control algorithm for a converter operating with a brushless direct current (BLDC) machine in the regenerative braking state. In the single-switched transistor control algorithm, the reverse current conduction phenomenon of power field-effect transistors (P-MOS) was introduced. As a result, the efficiency of the converter has been improved by about 10% compared to the previously known solutions. The new control algorithm has great implementation potential in electric-powered: bicycles, scooters, light cars, mild hybrid cars and small wind power plants.
