High speed motors are widely used due to the merits of high power density, small size and energy-saving. But there is no matched high-frequency inverter to drive high-speed motor. Therefore, study on high-speed motor special inverter becomes one of the key issues to accelerate application of highspeed motor. The influence of current harmonics on high-speed permanent magnet synchronous motor (PMSM)...
The characteristics of high-frequency and high-speed for high-speed permanent magnet synchronous motor have led to great difficulties for control. The starting and setting is complicated and losing synchronous easily. The current harmonics for the high-speed motor power supply is larger. The high-speed permanent magnet synchronous motor (PMSM) fuzzy-PID controller is proposed in this paper combined...
The square wave inverter with adjustable filter is proposed for high speed motor power supply. The six-step square wave inverter can reduce the switching frequency which is beneficial to high frequency inverter due to the switching frequency limitation. The adjustable filter combines low-pass filter with band-blocking filters which have adjustable inductance. The band-blocking filters can adjust the...
