Abstract :
A Single-Inductor Multi-Output (SIMO) DC-DC converter can generate various supply voltages with one inductor which can realize small size. Zero Voltage Switching (ZVS) can reduce switching loss which leads to high efficiency. In this paper, we propose a Single-Inductor Dual-Output (SIDO) boost converter with ZVS-PWM control and we show its simulation results; switching loss is reduced by 78%. Next, we describe design and experimental results of a Single-Inductor Single-Output (SISO) boost converter with ZVS-PWM control and we show that switching loss is reduced by 84.2%.
