99% Efficiency True-Bridgeless Totem-Pole PFC Based on GaN HEMTs
Liang Zhou, member IEEE and YiFeng Wu, member IEEE Transphorm, Inc. 75 Castilian Dr., Goleta, CA, 93117 USA [email protected] Abstract: This paper presents a true bridgeless totem-pole Power-Factor-Correction (PFC) circuit using GaN HEMT. Enabled by a diode-free GaN power HEMT bridge with low reverse-recovery charge, very-high-efficiency single-phase AC-DC conversion is realized using a t...
متن کاملA ZVT–ZCT PWM synchronous buck converter with a simple passive auxiliary circuit for reduction of losses and efficiency enhancement
Zero Voltage Transition (ZVT); Zero Current Transition (ZCT); Synchronous buck converter (SBC); Pulse width modulation (PWM) Abstract In this paper, a Zero-Voltage-Transition (ZVT)–Zero-Current Transition (ZCT) Pulsewidth Modulated (PWM) synchronous buck converter (SBC), with a simple passive auxiliary circuit is proposed, which reduces the stresses and improves the efficiency by pacifying the ...
متن کاملDesign and Simulation of New Efficient Bridgeless AC- DC CUK Rectifier for PFC Application
This project proposes a new AC-DC bridgeless CUK rectifier. The new bridgeless single-phase AC–DC power factor correction (PFC) rectifiers based on CUK topology are proposed. The absence of an input diode bridge and the presence of only two semiconductor switches in the current flowing path during each interval of the switching cycle result in less conduction losses compared to the conventional...
متن کاملAn Interleaved Totem-Pole Power Factor Correction Converter
This paper explains about basic working principles, implementation problems, and experimental results of a new power factor correction (PFC) topology. In this proposed topology, a totem-pole boost PFC circuit that works under interleaved critical-conduction-mode (CRM) condition is presented. The circuit is developed towards high efficiency, high performance, lowcost, simple control scheme, and ...
متن کاملNew Bridgeless DCM Sepic PFC Rectifier with Low Conduction and Switching Losses
New bridgeless single-phase ac–dc power factor correction (PFC) rectifier based on Sepic topology is proposed. The absence of an input diode bridge and the presence of only two semiconductor switches in the current flowing path during each switching cycle result in less conduction losses and improved thermal management compared to the conventional Sepic PFC converter. The proposed topology is d...
