Abstract

The current energy requirements of the residential, industrial, and commercial sectors are met by direct current (DC) electronic loads. Distributed generation (DG) systems which use photovoltaic systems, domestic wind generators, and grid integration, require maximizing energy transfer efficiency in these systems. The DC/DC converters integrated as interfaces between different sources of DG systems have the function to optimize the energy transferred to the DC bus. This paper proposes integrating a Quadratic Buck converter with reduced power processing as an interface between DG system sources and the DC bus. The design and operation of the converter in continuous conduction mode, as well as its average and linear models, are presented. The analysis of the reduced redundant power processing in the converter is also provided, along with the design of the DC bus voltage regulator.

为住宅直流微电网设计减少冗余功率处理的无变压器直流稳压器

目前，住宅、工业和商业部门的能源需求是通过直流（DC）电子负载来满足的。使用光伏系统、家用风力发电机和电网集成的分布式发电（DG）系统需要最大限度地提高这些系统的能量传输效率。作为 DG 系统不同能源之间的接口，集成的 DC/DC 转换器具有优化传输到直流母线的能量的功能。本文建议集成一个四次降压转换器，减少功率处理，作为风电机组系统源和直流母线之间的接口。本文介绍了转换器在连续导通模式下的设计和运行，以及其平均和线性模型。此外，还分析了转换器中减少的冗余功率处理，以及直流母线稳压器的设计。
