What was Wrong with Fryze’s Approach To Power Theory Development?
Prof. Stanisław Fryze, by developing his power theory (PT), made a fundamental contribution to studies on energy transfer in electrical circuits. After that, these studies were continued by scientists and engineers for several decades, and several new power theories were developed.

Piecewise Fryze power theory analysis applied to PWM DC–DC converters [PDF]
This study proposes an extension to the well‐known Fryze power theory, which allows the development of a mathematical procedure that defines a global factor for the active and non‐active power processing in pulse‐width modulated (PWM) dc–dc converters. This global factor is the dc power factor.

Determination of Inactive Powers in a Single-Phase AC Network
Based on the development of the theory of reactive power and distortion power, starting with the works of Fryze and Budeanu, it has been found that the contradictions in the definition of the components of inactive powers are caused by errors in the ...

This paper explores the potential of some remarkable power theories derived from Fryze’s approach to assessing waveform distortion contributions. The analysis is limited to a simplified system composed of one load and one voltage source connected by a point of common coupling.
