| Abstract |
In this contribution, the switching frequency based active power will be presented as a new power definition. Itcombines the information of the instantaneous power, as product of voltage and current, and the conventionalactive power representing the mean value of the instantaneous power over the fundamental period. Under severaltheoretical conditions the switching frequency based active power is absolutely equal to the well-known activepower definition. In practical applications it approximates the active power but with the advantage of considerationof highly dynamic load changes and transients in voltages and currents. Because of this aspect, it is very useful forreal time applications, especially for active power control. |
