Phase-shift PWM
Research on Phase-shift PWM Driving and Control of Traveling-wave Ultrasonic Motor
Ultrasonic motor is a new kind of actuator for motion control. Because of its special structure and different operating mechanism, ultrasonic motor has some prominent advantages which are different from the traditional electromagnetic motors. These characteristics make it has broad application prospects in non-continuous and accurate motion control fields. So, the study on ultrasonic motor’s [...]
Design of Battery Charger for Electric Vehicle Based on SOC Estimation Algorithm
With the increasing depletion of oil resources, and worsening environmental pollution, Fuel-engined vehicle will be gradually replaced by new energy vehicles. It is the inevitable trend. The moment, at home and abroad, a great deal of manpower and material resources have being invested in the development of new energy vehicles, particularly the study of electric [...]
