Abstract

This paper presents a high-efficiency adaptive active rectifier with fully digital feedback-based delay controllers (DFDC) to rapidly trace optimal on/off timing against input/load variations. Thanks to the real-time power-saving mode control, the proposed rectifier achieved high power conversion efficiency (PCE) of 93.5% and voltage conversion ratio (VCR) of 96.3%. The rectifier adaptively adjusts on/off timing with fast 13. 56MHz tracking loop bandwidth.
