摘要：
This paper presents a high-efficiency Schottky diode rectifier for the mobile wireless charging receiver. A wide input range multi-mode rectifier is proposed for a magnetic resonant wireless charging system. The configuration is automatically changed based on the input AC voltage to widen the input voltage range. It is fabricated in a 0.35 um BCD process and its area is Immxl. 5mm. When the magnitude of the input power is 4 W at 128 kHz, the Power Conversion Efficiency of the multi-mode Schottky diode rectifier is 85%, which is improved by 10% compared with that of the full-wave MOSFET rectifier.
