Abstract
In this paper, a single-phase two-stage zero-voltage-transition zero-current-transition pulse-width-modulation power-factor-correction (ZVT-ZCT-PWM-PFC) AC/DC boost converter with active snubber cell is presented, which can be interfaced with micro-hydro power plant and can be used for telecommunication, data center, and commercial building applications. Snubber cell facilitate all semiconductor switches to undergo soft-switching for every switching period. Proposed Converter operates in continuous-conduction-mode (CCM) and uses average current control scheme for PFC. Nearly unity-power-factor (UPF) operation is achieved for wide range of load. Design and analysis of a ZVT-ZCT-PWM PFC boost converter rated at 1 kW, output voltage 400 V, operating at 100 kHz, fed from AC voltage of 230 V RMS is presented. Proposed schematic is simulated in PSIM 9.0 and simulation results are provided. An efficiency of 97.8% and power factor above 0.998 is achieved at nominal power.
