N2 - In this paper, a cascaded multi-stage non-isolated high voltage conversion ratio (VCR) bidirectional DC/DC converter is proposed. The VCR is n times of the conventional buck/boost converter with only n+2 switches. All the switches can achieve full range ZVS whether in the buck or boost mode. The low voltage side current ripple can be reduced with two-phase interleaved structure, which is suitable for low voltage battery application. In addition, with only two small magnetic components, the power density of the converter is high. The operating modes, ZVS condition and design considerations of a four-stage topology are discussed in this paper. A 500W experimental prototype interfacing 20∼30V with 270V is built to verify the performance of the proposed converter.
