Abstract

The switching cell (SC) direct PWM ac-ac converters solve the commutation problem of traditional direct PWM ac-ac converters in a very effective way. The magnetic components of the SC ac-ac converters consist of two coupled inductors and an AC inductor. In order to make the SC ac-ac converters more useful and practical, this paper presents the integration of magnetic components in these converters in one magnetic core. The proposed integration method can significantly improve the power density of the SC ac-ac converters. In addition the cost of magnetic components and inductor coils can be reduced. In order to prove the validity of the proposed integration scheme a 600 W prototype inductor is built and tested.
