Reducing Electromagnetic Interference in Three-Level T-type Isolated Bidirectional DC-DC Converter Using a Snubber Circuit

Electromagnetic interference is the main problem in high switching power converters like DC-DC converters. One of solution methods for electromagnetic reduction to design a snubber circuit. The circuit practical method reduce fluctuations caused by parasitic components from layout and non-ideal characteristics devices. An effective increases converter's efficiency reduces EMI noise. In this paper, reduced using different circuits three-level T-type isolated bidirectional converter. converter simulated PSIM see effectiveness noise with circuits.
