Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 482)

Abstract

Aiming at the problem that between the second harmonic current i2nd and dynamic response characteristic of the middle bus voltage ub of the two stage inverter, the charge balancing controller integrated with the traditional double-loop controller is proposed. The traditional controller operates as load stable to suppress the secondary harmonic current i2nd, but the load switched by the new controller. Based on the traditional double-loop controller, the design of the voltage-loop controller that meeting requirements of i2nd is expounded, containing the influence of cross frequency ωc on Δub and the final dynamic response time ts of ub. The working principle of the electric-charge-balancing controller and some other key design issue are described. A prototype of 450 W is built to verify the correctness of the theoretical analysis and the feasibility of the new converter.
