摘要

本文介绍了一种三相四支路逆变器在源电压供电时作为有源滤波器，在电力系统故障时作为辅助电源(APS)的仿真。这项工作包括通过dc/dc双向变换器引入与三相逆变器相连的储能元件。这种dc/dc转换器在电池充电时用作“降压”转换器，或在电池提供负载时用作“升压”转换器。这种配置的目的是减少电池组的体积和重量。新系统(逆变器，dc/dc转换器和电池)必须根据电力系统的可用性在以下两种模式之一下工作:如果电网可用，作为有源电力滤波器和电池充电器，或者如果电网不可用，作为APS和升压。

Simulation of an inverter working as an active power filter and as an auxiliary power supply

This paper presents the simulation of a three-phase-four legs inverter working as an active power filter while the source voltage feeds the load, and functions as an Auxiliary Power Supply (APS) during a power system failure. This work consists in introducing an energy storage element linked to the three-phase inverter by means of a dc/dc bidirectional converter. This dc/dc converter works as a ¿buck¿ converter while the battery is recharged or as a ¿boost¿ converter when the battery supplies the load. The aim of this configuration is to reduce the bulky and heavy of the batteries bank. The new system (inverter, dc/dc converter and battery) has to work then in one of the following two modes according to the availability of the electric system: as an active power filter and battery charger if the grid is available, or as an APS and boost if the grid is unavailable.
