Abstract
An Improved LLC Resonant Converter with Re-configurable Hybrid Voltage Multiplier and PWM plus- PFM Hybrid Control for Wide Output Range Applications.
Abstract:
This paper proposes an improved LLC resonant converter with reconfigurable hybrid voltage multiplier (RHVM) for wide output voltage range applications. By adopting three legs and two active switches, the rectifier can be reconfigured to three configurations, i.e. full-bridge rectifier (FBR), hybrid voltage-multiplier rectifier (HVMR) and voltage-multiplier rectifier (VMR), covering the range of more than three times of the minimum output voltage. Compared with conventional LLC converter, the operating range of each configuration is narrowed so that the magnetizing inductance is optimized and switching frequency range is narrowed to achieve higher efficiency. Pulse width plus pulse frequency modulation strategy is employed to achieve smooth transition between these operation modes. Zero voltage switching of all power MOSFETs and zero-current switching of all secondary-side diodes are achieved as well.
