This work is dedicated to the development of a concept of universal converters. This concept lies in the utilization of the same semiconductors in the dc-dc and in the dc-ac configuration, resulting in minimal redundancy. The particular attention is focused on the phase-modular solution as a possible competitor to the earlier presented solution. The design example, comparative analysis between different modes is given. The experimental rated for 3.6 kVA power in the ac mode and 5 kW in the dc mode is presented. Pros and cons are discussed in conclusions along with possible fields of application.
