An Effective Charger for Plug-In Hybrid Electric Vehicles (PHEV) with an Enhanced PFC Rectifier and ZVS-ZCS DC/DC High-Frequency Converter

A plug-in hybrid electric vehicles (PHEV) charger adapter consists of an AC/DC power factor correction (PFC) circuit accompanied by a full-bridge isolated DC/DC converter. This paper introduces efficient two-stage topology with improved PFC rectifier as front-end and high-frequency zero voltage switching (ZVS). Current (ZCS) converter is the second part. The chosen bridgeless interleaved (BLIL) boost converter, it provides advantages like lessened input current ripple, capacitor electromagnetic interference. Resettable integrator (RI) control technique employed for DC regulation. controller achieves nonlinear makes more resilient faster transient response noise rejection. stage incorporates resonant circuit, which helps in achieving ZVS/ZCS inverter switches diodes. PI phase shift modulator used second-stage It improves overall efficacy lowering losses, stress on semiconductor devices, reversing recovery losses simulations experimental results infer that charging efficiency increases to 96.5%, 3% higher than conventional approach using
