【Abstract】 The voice coil motor has been applied widely as a linear actuator to generate forces with direct drive,fast response time,simple structure,etc. In order to maximize its performance,considering the principle of economy and performance,an architecture based on micro-controller and various analog circuit modules is proposed in the design of the driver. The micro-controller circuit,H full-bridge driving circuit,current measurement circuit,rectifier and filter circuit and various protection circuits are designed. By simulation and experimental results,the validity of the driver is verified successfully.更多还原
