Pulse-width modulation (PWM) of rated voltage waveform for three-level four-quadrant control-servo (4QS) e.g. for railway engineering
摘要
The method involves using pulse-width modulation (PWM) of a voltage in which a reference voltage is compared with a triangular (delta-form) waveform modulation signal. Timed sampled (tk) reference voltage values (u*) are compared with switching lines having maximum (ud) and minimum values (-ud) of the modulating signal.
