摘要
本文重点分析了AC-AC Buck变换器主电路的基本构成和工作原理,推导了变换方程,并通过仿真和实验验证了原理分析的正确性;文中还介绍了四象限开关的四步软换流策略,讨论了AC-AC Buck变换器能量双向流动的机理;最后,提出了以隔离式AC- AC变换器替代传统实验室用交流调压器、电力电子配电变压器的方案。
Analyzed the basic composition and operation theory, produced its transfer function, and tested the validity by simulation and experiment results;Introduced the four-step soft switching scheme and talked about the bi-directional energy flowing; Finally. introduced the method to compose an isolated AC-AC converter, proposed the two applications-power electronics ac Booster and power elec- tronics distribution transformer.
