Focus is on a transformer based single-switch galvanically isolated quasi-Z-source converter. Single-switch topologies suit well for low power applications due to low complexity and cost of realization. However, their performance is rather limited, since only one switch should handle all converter power. Input-parallel output-series (IPOS) cascading improves stress of semiconductor devices, reliability,...
This paper presents an analysis of the continuous current and the discontinuous current mode operation of the transformer of a step-up DC/DC converter topology intended for applications with widely changing input voltages. The proposed topology consists of a LC network coupled with a single-phase inverter on the primary side and a full-bridge rectifier on the secondary side of an isolation transformer...
This paper presents a new integrated (multiport) DC/DC converter for hydrogen-based energy storages. As compared to traditional individual converter based solutions, for interfacing of an electrolyzer and a fuel cell, the proposed topology features reduced energy conversion stages. In order to improve the response time of the hydrogen buffer the battery was integrated to the interface converter with...
