Modular design of soft-switching circuits for two-level and three-level inverters

  title={Modular design of soft-switching circuits for two-level and three-level inverters},
  author={Jie Chang and Jun Hu},
  journal={IEEE Transactions on Power Electronics},
This paper presents a negative-bus auxiliary resonant circuit (NBARC) and novel mirror symmetrical pair of resonant link modules for soft commutation of two-level and three-level inverters. The NBARC topology reduces the power device counts and requires low device power ratings. While the basic NBARC resonant circuit is conceived and analyzed for zero-voltage switching (ZVS) of two-level inverters, the topology and modular design approach are extended to form a pinched-link resonant stage of… CONTINUE READING
