Discussion on ``Three-Phase Power-Factor.'' Atlantic City, N. J., June 30, 1908

Discussions and Closures Discussion of “ Instantaneous Reactive Power - Theory and Power Properties of Three - Phase Systems ”

The author of the paper [1] should be commended for his continuous contributions pointing out the deficiencies of many of the available power theories. We fully agree with the author that the instantaneous p-q theory has important deficiencies when it comes to the physical interpretations of the power components. In [2], the author properly states that the main objectives of a power theory incl...

Three Phase Active Power Factor Correction in a Single Step

Resonant-Boost-Input Three-Phase Power Factor Corrector

This paper presents a novel three-phase power factor corrector (PFC) circuit which uses two power switches working in zero-voltage-switching (ZVS) condition. The two switches along with a high-frequency inductor constitute a high-frequency current source which is responsible for the energy transfer in the circuit. The input current is partly continuous and partly discontinuous. The total harmon...

Unidirectional Three Phase High Power Factor Hybrid Rectifier

Abstract – Power factor corrected rectifiers are new tendency in development of power supplies. This paper presents a brief review of some high power rectifiers structures and provides an assessment of each analyzed technology. As contribution, a novel hybrid high power rectifier topology is proposed and analyzed. An active unidirectional three phase rectifier is associated in parallel with a t...
