Grid connected unity power factor converters based on one cycle control (OCC) do not require the service of PLL or any other synchronization circuits for interfacing with the utility. As a result, these schemes are becoming increasingly popular. However, as the power handled by the converter increases, the power factor deteriorates. To understand quantitatively the cause of poor power factor while...
AC-to-DC converters based on one-cycle control exhibit instability in current control at light load conditions as well as when they are operating in the inverting mode. In this paper, a modified one-cycle controller for bidirectional AC-to-DC converter is proposed. A fictitious current component in phase with the utility voltage is synthesized. The sum of this current component and the actual load...
AC to DC converters based on one cycle control (OCC) exhibits instability in current control at light load conditions as well as when it is operating in the inverting mode. In this paper a modified OCC for a bi-directional AC to DC converter is proposed. The proposed technique neither requires the knowledge of the 60deg angular sectors of input voltage nor it requires the service of additional multiplexers...
