Abstract
The high efficiency soft switching bridgeless PFC rectifier with Continuous Conduction Mode (CCM) is proposed for Neighbourhood Electric Vehicle (NEV). For each switching period, the proposed converter operates both in Pulse Width Modulation (PWM) mode and resonant mode and hence termed as Hybrid Resonant PWM. Reduced Electromagnetic Interference (EMI), switching losses and voltage stress across semiconductor devices are realized in this converter by implementing the soft-switching technique. Externally Resettable Integrator (ERI) Control technique is employed in which the duty ratio control of the switch is achieved in a single switching period. This technique also rejects input voltage perturbations in one switching cycle and follows the control reference instantaneously. A 125W converter prototype is designed and simulated using PSIM software and the results are realized with experimental results. The hardware results infer that the input power factor is closer to unity and output voltage is regulated to 110V with an efficiency of 94%. © 2020 Institut za Arhitekturu i Urbanizam Srbije.
