A study of the fundamental of operation of a three-phase AC-DC power converter that uses Zero-Voltage Transition (ZVT) together with Space Vector Pulse Width Modulation (SVPWM) is presented. The converter is basically an active rectifier divided into two converters: a matrix converter and an H bridge, which transfer energy through a high-frequency transformer, resulting in a modular AC-DC wirel...

An isolated dual-input power converter for a grid/photovoltaic (PV) hybrid power indoor lighting system is proposed in this paper. The proposed converter can be operated in single power supply mode or hybrid power supply mode. While the available PV power is insufficient for the load demand, the proposed dual-input converter will automatically deliver the complement power from the grid. The pow...

Fuel cells are new alternative energy resource that has a great promise for distributed generation and electric vehicle application. However, fuel cells have a slow response due to their slow internal electromechanical and thermodynamic response. To optimize the fuel cell system performance, a fuel cell DC-DC converter with an appropriate controller which can regulate the power flow and automat...

The loading of free wheel diodes (FWD) and IGBTs in the power modules of a Voltage Source Converter (VSC) are investigated. In converter duty, the FWD is utilized more then the IGBT. Presently, most FWD’s in power modules are optimized for inverter duty. This practice tends to undersize the FWD from a converter viewpoint. This design philosophy is examined in the paper. For this purpose, the or...
