   A New Active Clamp Sepic-Flyback Converter for a Fuel Cell Generation System
By Tae-Won Lee, Soo-Seok Kim, Yuen-Chung Kim, Chung-Yuen Won, Kee-Hwan Kim [View]
[Download]

Abstract: In this paper, a new active clamping sepic-flyback converter has been proposed, which is suitable for a fuel cell based power generation system. The proposed converter is superposition of sepic converter mode and flyback mode. It has outstanding high boosting output voltage, component utilization and high efficiency characteristics under the inherently severe low output voltage of the fuel cell generator. The proposed converter for a full cell generator is described and verified by simulation and experimental result that make used of the Proton Exchange Membrane Fuel Cell (PEMFC) Generator.

   Connecting Small Wind Turbine to a Site-Wide DC BUS
By S. Sathiakumar, A.R. Turner, Y.S. Lee [View]
[Download]

Abstract: An alternative to energy produced by fossil fuels is the wind energy, which is a clean and renewable alternative. The bulk of currently available wind power is produced on large wind farms, which are operated by power companies. These wind farms use up vast amounts of space, and are usually located away from residential areas. One way to make better use of available land would be to allow institutions to install small windmills on their own properties. These small windmills would help to offset the load placed on the grid by the residence. A DC–DC converter for such application is presented and the control method discussed to inject power from a small wind turbine into a site-wide DC bus.

   Variable Speed Integrated Generator System with LC Output Filter Connected to the Grid Distorted Voltage
By Emil Ernest, Wlodzimierz Koczara, Nazar Al-Khayat [View]
[Download]

Abstract: The paper presents variable speed integrated generator set driven by internal combustion engine and permanent magnet generator supplying ac/ac converter. The system operates autonomously and grid connected. When VSIG set is connected to grid, then the non-sinusoidal current component is produced by the output capacitor which is directly connected to the grid distorted voltage. The paper presents controller strategy and discusses the technique of harmonic compensation of the output capacitor by active current injection method. Analysis of modeling and laboratory tests of the 40kVA generation system will be presented in paper.

   Ferroresonant Transformer, PWM- and Matrix-Converter in Rural Micropower Generation
By Mario Pacas, Martin Schulz [View]
[Download]

Abstract: The development of electric components for micro power plants for rural applications is evaluated by comparing different topologies with cost functions chosen according to the application. A test bench was developed to emulate the prime movers characteristic; magnetic voltage stabilization, PWM inverter and matrix converter were examined as possible solutions for power electronic. The waterwheel and the windmill were chosen as prime movers.
