Power converters for high speed electrical machines


High speed electrical machines for aerospace, wind or co-generation applications need power converters tailored to produce high frequency waveforms using only reduced switching frequency to do not compromise efficiency. In the design of such power converters there will be analyzed new multilevel and multicell topologies and new design trends such as those based on the Power Electronics Building Block. Hence new modulation strategies and current control strategies will be needed. There will be designed hardware platforms to measure the electrical quantities, control them using DSP and FPGA, driving of the semiconductors and the due protections. The aim will be to guarantee the operation at elevated frequencies, without compromising the efficiency and minimizing the encumbrance due to the harmonic filtering stage typically required in traditional passive solutions
