Abstract |
In this paper a two-parallel inverter topology is introduced which combines the advantages of IGBT'swith the benefits of SiC-MOSFET's to achieve an ideal output current. The common control algorithmwhich is implemented on a FPGA utilizes the IGBT inverter for carrying the major load current, whilethe SiC inverter is only used for ripple current compensation. In this configuration the system provides an active current harmonic canceling technique with the potential to save passive filter elements. This paperpresents a mathematical model to characterize the circulating currents and to design an ideal controllerthat can be used to identify the theoretical limits of the system. A first practical implementation on testbench with corresponding measurement results demonstrate the feasibility and benefit of the proposedhybrid inverter structure. |
