Proposal Of A Control Algorithm Applied To A Threephase, Four Wire, AC-DC Converter For EV And UPS Applications
This paper introduces a control algorithm for a multifunctional, three-phase, four-wire ac-dc converter. The converter is so-called multifunctional because it operates as a battery charger and as a load power supply. In other words, two different loads in parallel are simultaneously connected to the...

| Sumario: | This paper introduces a control algorithm for a multifunctional, three-phase, four-wire ac-dc converter. The converter is so-called multifunctional because it operates as a battery charger and as a load power supply. In other words, two different loads in parallel are simultaneously connected to the converter. The proposed algorithm can be applied to nonisolated three-phase UPS (uninterruptible power supply) systems, and electric vehicle (EV) battery charging systems. Relevant features of the proposed approach are power factor correction, common neutral point between the input and output facilitates the installation of the bypass circuit, balanced and symmetrical output voltages that allow the use of inverters with neutral point, and control of the battery current. The operation principle of the proposed algorithm is discussed in detail, while experimental results are also presented. |
