Regulating m-pulsed a.c. currents involves varying sampling time and switching frequency of converter in targeted manner, e.g. depending on phase angle of currents |
摘要 |
The method involves cyclically varying the sampling time and hence the switching frequency of the converter in a targeted manner. The sampling time and switching frequency can be varied depending on the phase angle of the currents. The fundamental oscillation is detected by forming the means (8) of the voltage and current over one or more voltage periods.
