Abstract

A contemporary model of a single phase bridgeless AC-DC buck boost converter has been proposed to strengthen the overall performance of conventional AC-DC converter. Use of single switch and bridgeless topology makes the proposed topology a suitable choice compared to other existing AC-DC converter topology. The conventional AC-DC converters with bridge configuration supply a pulsating ripple signal to the input of the converter circuit which creates lots of disturbance in the overall power system. Due to absence of bridge rectifier such problems do not arise in the proposed converter and it has also resolve the problem of using high value filtering element at the input side. Comparisons are being made between proposed and conventional converters. Comparison analysis makes it clear that proposed AC-DC converter performed better than conventional converters. The performances of the converter circuit have been monitored by software circuit simulation employing PSIM 9.1.1.400 environments.

高质量单相交直流降压升压变换器的性能分析

为了提高传统交直流变换器的整体性能，提出了一种新型单相无桥降压升压变换器。与其他现有的交直流变换器拓扑相比，使用单开关和无桥拓扑使所提出的拓扑成为一个合适的选择。传统的桥式交直流变换器向变换器电路的输入端提供脉动纹波信号，对整个电力系统产生很大的扰动。由于没有桥式整流器，该变换器不存在上述问题，并且解决了输入端使用高值滤波元件的问题。正在对拟议的和传统的转换器进行比较。对比分析表明，所提出的交直流变换器性能优于传统变换器。采用PSIM 9.1.1.400环境对变换器电路的性能进行了软件仿真。
