| Abstract |
Hydrogen as storage medium for fluctuating renewable energy generation requires high current, lowvoltage rectifiers for grid integration and feeding of the electrolyzer. One topology for an efficient androbust rectifier, capable of supporting the grid, is the combination of well-known thyristor basedrectifiers with a PWM based active rectifier. The thyristor rectifier will be designed to deliver the mainpart of the output current. Hereby the aim is to use smallest possible passive components. The activerectifier has the purpose of correcting the input current waveform while automatically correcting theoverall output current to the desired direct current.The Boundary conditions for the desired application are shown, as well as the implementation and thecontrol considerations. The basic concept is then proved by simulation. For the basic topology,consisting of a six pulse thyristor rectifier and six-MOSFET full bridge experimental results areshown. |
