Analytical Model for Losses Mitigation in Series Power Electronic Converter

Series Power Electronic Converter (SPEC) is an effective device in compensating continuously the RMS voltage variations in a low voltage network, downstream the point of installation. The SPEC is designed to use only reactive power for the voltage compensation and permits to reduce cost of operation and maintenance, even though it can impose some operating limits. In literature, works on single phase SPEC related to operating principle, limitations and devices control for compensation of network voltage under load and renewable energy variations are presented. However, works related to its active power management to meet its device losses are often not considered and seldom presented in the literature. In this work, for single phase SPEC to manage the compensation and at the same time its device active power needs, analytical and graphical analysis models are presented from a generic theoretical approach along with the imminent boundary conditions for the device operation.
