PROJECT TITLE :
Anti-EMI Noise Digital Filter Design for a 60 kW 5- level SiC Inverter without Fiber Isolation - 2017
ABSTRACT:
Silicon carbide (SiC) power devices are helpful to the converters in terms of size reduction and potency increase. Nevertheless, the fast switching of SiC devices ends up in additional serious electromagnetic interference (EMI) noise issue. Optical fibers based mostly isolation provides a reliable answer to block the EMI noises from the ability circuit to the management circuit however with further cost and size penalty, especially for multilevel converters. This letter aims at the digital filters primarily based answer to suppress the sampling noise caused by EMI without any additional hardware value. An improved median filter and a novel magnitude bandpass filter are proposed. The design tradeoffs among noises filter capability, delay result and the computation time have been discussed for proposed filters. The anti-EMI noise perform of proposed filters has been experimentally verified in a very 60-kW five-level SiC inverter.
