摘要

无桥拓扑结构已被引入，以提高输入功率因数，从而减少THD和输入电流的波纹。无桥zeta变换器具有半导体开关数量少、电气隔离容易、启动时涌流小等优点。传统的PWM技术用于开关的控制。但存在动态响应慢的问题。使用单周期控制，可以在一个开关周期内消除输入扰动。本文对无桥变换器的传统PWM技术和改进的单周期控制技术进行了比较。利用MATLAB/Simulink建立了该模型，并对结果进行了分析。

Comparison of PWM and modified One Cycle Control for bridgeless zeta AC-DC converter

Bridgeless topologies have been introduced to improve the input power factor and hence reduce THD and ripples in the input current. Bridgeless zeta converter has the advantages of reduced number of semiconductor switch, easy electrical isolation and reduced in-rush current during start-up. Conventional PWM technique is used for the control of switches. But it suffers from the problem of slow dynamic response. With One Cycle Control it is possible to eliminate input perturbations in one switching cycle. In this paper, a comparison has been made between the conventional PWM technique and modified One Cycle Control for bridgeless zeta converter. The model is developed using MATLAB/Simulink and the results have been analyzed.
