Abstract

The development of dc grids requires compact, economical, and efficient means of dc–dc integration. The parallel hybrid converter (PHC) is a suitable candidate for dc–dc integration due to its low energy storage requirement (ESR), soft switching, low submodule (SM) and switch count. However, the requirement of large dc side filtering and harmonic voltage injection (HVI) have been crucial limitations of the PHC. This article proposes a new modulation scheme to eliminate the need of dc filter inductor. The design steps and comparison with existing modulation scheme are briefed. The effectiveness of the proposed modulation scheme is validated on a developed three-phase front-to-front experimental setup.

并联混合DC - DC变换器抑制DC链路滤波的无纹波调制方法
直流电网的发展要求采用紧凑、经济、高效的直流集成方式。并联混合变换器(PHC)具有低储能要求(ESR)、软开关、低子模块(SM)和开关数等优点,是dc-dc集成的理想选择。然而,对大直流侧滤波和谐波电压注入(HVI)的要求一直是PHC的关键限制。本文提出了一种新的调制方案,消除了对直流滤波电感的需要。简要介绍了设计步骤,并与现有调制方案进行了比较。所提出的调制方案的有效性在开发的三相前端对前端实验装置上得到了验证。
