Abstract

In this paper is proposed an integrated power electronics solution able to connect a distributed generation (DG) system with a hybrid dc/ac microgrid. One of the main advantages of the proposed converter is high level of integration with reduction of one power switch, while keeping the same features of the conventional solution, such as (i) bidirectional power flow between dc and ac micro-grids, (ii) independent control in both dc and ac parts, and (iii) different operation conditions using a unique power conversion circuit. Despite proposing a new solution, this paper presents the converter models and an analysis of the converter in terms of its operation and PWM strategy, as well as the analysis of the power flow among different elements employed in the system.

新型电力电子变换器与直流/交流混合微电网相连接
本文提出了一种集成电力电子解决方案,能够将分布式发电系统与直流/交流混合微电网连接起来。所提出的变换器的主要优点之一是集成度高,减少了一个电源开关,同时保持了传统解决方案的相同特征,例如(i)直流和交流微电网之间的双向功率流,(ii)直流和交流部分的独立控制,以及(iii)使用独特的功率转换电路的不同操作条件。尽管提出了一种新的解决方案,但本文给出了变换器的模型,并分析了变换器的工作原理和PWM策略,以及系统中不同元件之间的功率流分析。
