“…Most of these precise devices need steady and clean power to function properly. With this in view, several standards have been proposed to restrict the power quality, such as the IEEE 519 adopted by the United States, the IEC 555 or the IEC 1000-3-2 Europe adopted [1][2][3]. To meet these standards, it is common to add power factor correction circuit and uninterruptible power supply into such devices to improve the system stability.…”

A single-stage DC uninterruptible power supply (UPS) is proposed in this paper. Basically, the proposed converter is an integration result of a power factor correction circuit with a dc-to-dc converter to achieve simple hardware circuit, high efficiency, and low cost for extra UPS function. Under normal operation, a novel two-switch SEPIC converter operates as an ac to dc converter with sinusoidal input current, unity power factor, and low ripple dc output voltage, and as a battery charger if a battery is added. Since both the input boost supply and the output supply can be controlled independently, a fast transient response can be maintained at both the input for active current wave shaping and at the output for good output regulation. When the ac source is in an outage condition, the proposed converter functions as a dc-to-dc buck-boost converter; therefore, the desired dc output voltage can be provided. Finally, some experimental results are presented for verification.

“…However, using such devices may result in large harmonic currents injected into the utility grid resulting into harmonic pollution; degradation of power quality is imminent [1]. With this in view, several standards have been proposed to restrict the power quality, such as the IEEE 519 adopted by the United States, the IEC 555 or the IEC 1000-3-2 Europe adopted [2][3][4][5]. To meet these standards, it is important that the interface with utility draws as near a sinusoidal current as possible.…”

A single-phase two-switch SEPIC AC to DC converter is proposed in this paper. The boosting supply of the input is controlled by PWM of the power stage, while the desired DC output is PWM controlled. Since both the input boost supply and the output supply can be controlled independently, a fast transient response can be maintained at both the input for active current wave shaping and at the output for good output regulation. In addition, independent control of the multiple outputs provides the strong decoupling necessary and hence good transient response. Finally, some experimental results are presented for verification.
