ABSTRACT
Abstract:
The demand for power converters is on the rise due to their ability to achieve higher power conversion efficiency, smaller size, light weight and reduced cost. DC-DC converters are used in many applications where, the output voltage needs to be regulated for wide variations in the input voltage and the load. They are also used in applications where electrical isolation is required. Power generation from renewable energy sources suffer from highly fluctuating output voltages. Electrical isolation of renewable energy sources from the grid is essential. Therefore, DC-DC converters are used as an integral part of the power electronic interface required for grid integration of renewable energy sources such as wave energy power conversion. For a 'fixed-frequency ZVS integrated boost dual three-phase bridge DC-DC LCL-type series resonant converter', the working, modeling and the steady-state analysis using approximate complex ac circuit analysis method has been done. A 50 to 100 V input, 600 W, 190 V output, DC-DC converter operating with 100 kHz switching frequency has been designed. The performance of the designed converter has been verified by using PSIM simulations and by building an experimental model. The findings are being presented.
