Originated from analyzing nonactive power loss, a novel optimization method and modulation solution for bidirectional isolated dual-active-bridge (DAB) dc–dc converters are proposed in order to achieve high efficiency in a wide operating range. A comprehensive nonactive power loss model is developed, including both the nonactive components delivered back to the source and from the load. This paper...
A single inductor three-level boost bridgeless PFC rectifier with nature voltage clamp is proposed. In the proposed converter, the operation principle is quite different from other boost bridgeless three-level converters. The charging stage is presented in the low side while the discharging stage in the high side and vice versa. As a result, nature voltage clamp is achieved. And the slow diodes are...
A novel soft-switching single-stage power factor correction (PFC) converter based on current-fed full-bridge topology is presented in this paper. First, the operation principle and characteristic are analyzed in details in this paper. Zero-voltage-transition which reduces stress of main switches is achieved; furthermore, both the voltage spike and loss induced by stubborn leakage inductor of isolation...
