Abstract
A current-fed bridgeless interleaved power factor correction rectifier
with voltage-doubler characteristic is proposed for a hybrid electric vehicle
charging system. The simulated efficiencies, Total current Harmonics current
Distortion (THDi), and Power Factor (PF) for the bridgeless interleaved
Power Factor Correction (PFC) converter are presented in this paper. The
differences of the simulated THD and PF between the proposed PFC boost
converter and the conventional interleaved PFC boost converter are significant.
The simulation results included a prototype boost converter converting
universal AC input voltage 85–264 V to 400 V DC output at up to 3.4 kW
load. The simulation results also demonstrate a power factor greater than
0.99 from a universal AC-line input 85–264 Vrms; THD <10% from a universal
AC-line input 85–264 Vrms. The proposed converter achieved an average efficiency
of 97% at 70 kHz switching frequency, 264 V input, and 0.5–3.4 kW output
power. The proposed interleaved boost PFC rectifier exhibits an improved
low-line efficiency compared with that of its conventional counterpart
under 1.5 kW output power.
