Purpose

This paper aims to propose Hidden Converter (H-Converter) combined with dual port 3Ø inverter for energy storage application to produce wide range of voltage. Some of the application required wide range of voltages, but problem from E-chopper is either boost or buck mode of operations, both modes are not possible. To overcome this drawback, H-Converter is combined with dual port 3Ø inverter controlled by carrier-based pulse width modulation (CB-PWM) technique is added with zero sequence injection.

Design/methodology/approach

Hidden converter is a bidirectional DC-DC chopper used to convert fixed DC to variable DC and vice versa in both buck and boost modes of operations. Dual port inverter is combined with hidden DC-DC converter can produce wide range of voltages.

Findings

The bidirectional DC-AC converter requires less power for processing and consumes less power losses by using modest carrier built- pulse width modulation scheme through proposed zero structure addition.

Originality/value

By using this proposed strategy H-Converter can produce wide range of voltage in both the sides and mostly power is processed in the 3Ø inverter with a one stage conversion with less power loss. As a result, with one stage power conversion has more efficiency because of less power loss. This proposed converter has designed by analysis, and the real time result is tested in an experiment.

使用 H 转换器的集成 DC-AC 和 AC-DC 转换器，适用于宽范围电压应用

目的

本文旨在提出隐式转换器（H-Converter）与双端口3Ø逆变器相结合的储能应用，以产生宽范围的电压。一些应用需要很宽的电压范围，但 E-chopper 的问题是升压或降压操作模式，这两种模式都不可能。为了克服这个缺点，H-Converter 与双端口 3Ø 逆变器相结合，该逆变器由基于载波的脉宽调制 (CB-PWM) 技术控制，并添加了零序注入。

设计/方法/方法

隐藏转换器是一种双向 DC-DC 斩波器，用于在降压和升压操作模式下将固定直流转换为可变直流，反之亦然。双端口逆变器结合隐藏式DC-DC转换器可产生宽范围的电压。

发现

双向 DC-AC 转换器通过提议的零结构添加使用适度的载波内置脉宽调制方案，需要更少的处理功率并消耗更少的功率损耗。

原创性/价值

通过使用这种建议的策略，H-Converter 可以在两侧产生宽范围的电压，并且大部分功率在 3Ø 逆变器中处理，具有较少功率损耗的一级转换。因此，由于功率损耗较小，一级功率转换具有更高的效率。该转换器是通过分析设计的，并在实验中对实时结果进行了测试。
