Abstract:
|
In general, Voltage distortion is existed between the reference and the actual output voltages in a
pulse-width-modulated voltage-source inverter. This distortion is dead-time effects, which caused by the deadtime
setting and the trailing effect of non-ideal switching characteristics of the optical coupler and power
devices. To improve the performance of the drive system effectively, this study presents a novel dynamic deadtime
compensation, which is based on the device characteristics and the running conditions of the motor.
Finally, the results of experiment verify its validity.
Key words: Dead-time effect, dynamic compensation, the trailing effect, , , ,
