Three single phase transformers are used in star connection whose primary is connected to the 3 phase supply. The secondary ends of 6v are connected in parallel, which produces net output voltage of 0 v whenever all phases are present and nearly 6 v when any one of the phase fails.
A single-phase transformer is a type of power transformer that utilizes single-phase alternating current, meaning the transformer relies on a voltage cycle that operates in a unified time phase. They are often used to step-down long distance and localized transmission currents into power levels more suitable for residential and light-commercial.
Single-wire earth return (swer) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at low cost. Its distinguishing feature is that the earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second.
In this paper, a high performance single phase transformer-less online uninterruptable power supply (ups) is proposed. The use of the bidirectional buck-boost converter with high conversion ratio not only reduces the number of batteries but also ensures a transformer-less system. The rectifier has capability of power factor correction and provides regulated dc link voltage whereas the inverter.
