Voltage sag are the most common and cause more economic losses, which is a serious power quality (PQ) problem. To solve these problems, several topology using an extra battery or back-to-back has been introduced. However, these conventional topologies have drawback in cost effective and system reliability. This paper presents a three-phase voltage sag supporter for power distribute systems known as dynamic voltage restorer (DVR), and is employing direct ACAC converter using switching cell (SC) structure. The ACAC converter, in proposed supporter, is highly reliable because they can solve the shoot-through, dead-time, and commutation problem of traditional AC-AC converters without voltage/current sensing devices from SC structure. Moreover, the proposed voltage supporter has a good dynamics because it operates immediately by using interphase voltage when voltage sag is occurred in grid. Simulation and experimental results is provided to verify this.
