Evaluation of instantaneous power terms in multi‐phase systems: techniques and application to power‐conditioning equipment

Abstract

Abstract This paper presents a general control method that fully utilizes the inherent capability of AC‐fed PWM converters to compensate for reactive and harmonic currents absorbed by other loads. For this purpose, suitable definitions of instantaneous active and reactive current and power terms are introduced. Simulated results demonstrate the capabilities of the proposed compensation method, which can also be implemented in existing systems, as only modifications of the control section are needed.
