Unified power electronic load for burn-in test

Abstract

By defining power electronic load cell (PEL cell) and adopting different control strategies, the application of power electronic load for both AC and DC source is presented in this paper. A unified power electronic load is proposed which is composed of three basic PEL cells. Improved repetitive control is proposed to improve the dynamic performance of the system. Theoretical analysis and simulation results verify the validity of this unified power electronic load.
