Abstract

Zero-Voltage-Switching Quasi-Resonant Boost Converter (ZVS-QR boost converter) is a DC-DC boost converter that uses a resonant circuit for the purpose of achieving zero-voltage switching (ZVS) of the main switch, which reduces switching losses and enhanced overall efficiency. The ZVS-QR Boost converter with M-type switch topology utilizes a single switch and minimal auxiliary components, such as an inductor and a capacitor, which contributes to its simplicity, cost-effectiveness, high power density, high efficiency, and low electromagnetic interference (EMI). This paper presents the analysis, modeling and design of ZVS-QR Boost converter with M-type switch. The equations describing converter operation are derived. The quality factor, power losses and electromagnetic interference (EMI) of the proposed ZVS-QR Boost converter with M-type switch topology can be compared to those of a conventional boost converter. the conventional dc-dc boost converter and ZVS QR boost converter are simulated using MATLAB/SIMULINK.

具有可变输入电压和负载的ZVS QR升压转换器

零电压开关准谐振升压变换器(ZVS- qr升压变换器)是一种利用谐振电路实现主开关零电压开关(ZVS)的DC-DC升压变换器，降低了开关损耗，提高了整体效率。具有m型开关拓扑的ZVS-QR升压转换器利用单个开关和最小的辅助元件，如电感器和电容器，这有助于其简单，成本效益，高功率密度，高效率和低电磁干扰(EMI)。本文介绍了带m型开关的ZVS-QR升压变换器的分析、建模和设计。推导了描述转炉运行的方程。本文提出的具有m型开关拓扑的ZVS-QR升压变换器的质量因子、功率损耗和电磁干扰(EMI)可以与传统的升压变换器进行比较。利用MATLAB/SIMULINK对传统dc-dc升压变换器和ZVS QR升压变换器进行了仿真。
