A Zero-Voltage Switching Buck Converter With Enhanced Efficiency Over a Wide Load Range

A Zero-Voltage Switching Buck Converter With Enhanced Efficiency Over a Wide Load Range 150 150
Author(s): Jingyi Yuan, Qingqing Min, Siyang Liu, Lin Cheng

Abstract:

This article presents a wide-input-range buck converter featuring a conduction-loss-minimized zero-voltage switching (ZVS) technique. The proposed ZVS topology enables accurate ZVS operation across a wide range of input voltage ( $V_{\mathrm {IN}}$ ) and load current ( $I_{\mathrm {O}}$ ). By keeping the auxiliary inductor current pulse in the ZVS branch separate …

Abstract:

A fully integrated galvanic isolator for gate drivers that supports high-speed, asynchronous, full-duplex communication is presented. Data transmission from the microcontroller to the power device is achieved using amplitude-shift keying (ASK) at 100 Mb/s, while simultaneous communication in the opposite direction is implemented using frequency-shift keying (FSK) at 167 Mb/s. …
