摘要

This paper presents a novel unity power factor fuzzy battery charger conception based on an ultrasparse matrix rectifier (USMR). The advantages of the proposed converter are low harmonic distortion in absorbed currents and nearly unity power factor over a wide operating output power range. Its circuit has only three switching components and low-energy-conversion loss. This reduces the cost and enhances the system's efficiency for high-voltage battery. Thus, the proposed fuzzy logic controller improves the line power quality and delivers admissible output power to the battery. Experimental results based on a 24-V battery charger are proposed to validate the proposed approach and to demonstrate its performance. The stability and performance of the battery charger are then verified by the constant current and constant voltage charge. The fuzzy control and space vector modulation algorithms are implemented with the Digital Signal Processor.
