Active Rectifier for Uninterruptable Power Supply
The paper contains analysis of power factor correction circuits that is made in the context of elaboration of uninterruptable power supply system. Various correctors have been estimated analytically, by means of simulation and experimentally. The most significant attention has been paid to the efficiency of the analyzed converters and their compatibility with modular approach to development of ...
متن کاملA New Approach for Reactive Power Control of Single Phase Transformerless Inverter to Modify Power Quality in Stand Alone Micro-Grids with Current Leakage Elimination
Nowadays there has been an increasing interest in transformerless inverter for grid-connected photovoltaic (PV) system due to low cost, high efficiency and light weight. One of the reasons describe the grid behavior is capability of reactive power control by inverter. According to the standard VDE-AR-N 4105, grid-tied PV inverter of power rating below 3.68KVA, should attain power factor (PF) fr...
متن کاملControl of Transformerless Uninterrupted Power Supply for Unity Power Factor and Sinusoidal Inductor Currents
This paper discusses the design of controller for transformerless uninterruptible power supply (UPS), with simultaneous ac and dc loading. The objective of the design is to maintain good regulation of the ac and dc voltages and sinusoidal inductor currents simultaneously. The volt-second balance across the output filter inductor is used to maintain the current in sinusoidal form which is the un...
متن کاملSeries-Resonant Single-phase AC-DC Power Supply with Control of Reactive Power
The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in dc-dc conversion. This technology transfers bulk energy efficiently through a series-resonant circuit in the direct path of the energy transfer. This resonant converter forms a high-frequency ac link between the voltage sources connected to the input and output terminals. The...
متن کاملEvaluation of Single Phase Transformerless Photovoltaic Inverters
Transormerless inverters are attractive solution for the grid connected photovoltaic (PV) systems. Unfortunately, it has issues on galvanic isolation between PV systems to the grid. When the galvanic isolation disappears from the PV inverter, leakage currents will flow in a resonant circuit formed by the ground capacitance, the converter, the ac filter and the grid. In order to avoid the leakag...
