Abstract
On the demand of miniaturization,high efficiency and high reliability for underwater brushless DC motor propulsion system,phase current reconstruction synchronous rectification control about the controller with single current sensor between power supply and bridge arm capacitance was researched on. The commutation characteristics of brushless DC motor were analyzed,and then the phase current reconstruction method was given based on DC bus current in different conduction intervals. Furthermore,the synchronous rectification control with phase current closed-loop was realized. Simulation and experiment results verify the method.关键词
