Fryze - Buchholz - Depenbrock: A time-domain power theory
2008 International School on Nonsinusoidal Currents and Compensation, 2008Several power theories trying to explain the difference between the physically defined active power and the apparent power are known - and under discussion. This paper gives an overview of a universal time-domain power theory mainly developed by Fryze, Buchholz and Depenbrock. It is verified by theoretical considerations and explained by examples.

Fryze power theory with adaptive-HCC based active power line conditioners
2011 International Conference on Power and Energy Systems, 2011This paper presents a Fryze power theory based three-phase, three-wire Active Power Line Conditioner (APLC) for power quality enhancement. The shunt APLC system is used for harmonics and reactive power compensation due to non-linear loads. The compensation control strategy is proposed on active and non-active power in the time domain based generalized ...

Deficiencies of Fryze’s Power Theory
Abstract Fryze introduced a few important and permanent ideas to power theory, such as the concept of the active current and the concept of orthogonality of the current components. According to his power theory, the power properties of electrical circuits should be specified in the time domain, without using the concept of harmonics ...openaire +3 more sources
Electrical Engineering, 1997 The development of power theory of circuits with nonsinusoidal voltages and currents was shaped for several decades by two different approaches introduced, separately, by Budeanu and Fryze in the nineteen thirties. This paper investigates these two power
