Abstract
A power converter topology suitable for online single-phase uninterruptible power supply (UPS) systems is presented. The converter uses only four switches, five if a low-voltage battery and resonant link operation are required, to realize very desirable features. These include independent control of the input and output currents a common neutral connection, line conditioning, sinusoidal input currents independent of load current, and battery charge/discharge regulation. Detailed simulation results and experimental results are included.<>
