摘要

目的提出一种基于双向隐藏变换器(BHC)的三相DC-AC转换储能系统。BHC是将储能装置电压变化到大范围的新概念。采用基于零序注入的载波脉宽调制(CBPWM)策略降低了隐变换器的功率损耗和额定功率。通过使用这种控制策略，BHC在双级转换过程中只处理少量功率，大部分在三相三端口转换器(TPTPC)的直接或单级转换过程中只处理最大功率。发现stptpc由两组用于逆变过程的正组开关组成，一组开关为常规逆变开关，称为垂直正组开关，另一组为反串联开关，水平连接，用于直接或单级转换。分析了所提出的直流-交流3Ø转换系统及其PWM策略的特点、原理和实现。通过实验结果，验证了所提解决方案的有效性和可行性。

TPTPC and BHC integrated grid connected energy storage system for power loss reduction

Purpose This paper aims to propose a bidirectional hidden converter (BHC)-based three-phase DC–AC conversion for energy storage application. BHC is the new concept to vary an energy storage device voltage into wide range. Hidden converter power loss and power rating are reduced by using zero-sequence injection-based carrier-based pulse-width modulation (CBPWM) strategy. Design/methodology/approach By using this control strategy, a BHC processes only little amount of power during double-stage conversion, mostly during direct or single-stage conversion of the three-phase three-port converter (TPTPC) only processing the maximum power. Findings TPTPC consists of two sets of positive group switches for inversion process, one set of switches is regular inverter switches called vertical positive group switches, and the second set is anti-series switches, which are horizontally connected for direct or single-stage conversion. Originality/value Characteristics, principles and implementations of proposed DC–AC 3Ø conversion system and its PWM strategy are analyzed. Through experimental outputs, the effectiveness and viability of the proposed solutions are validated.
