Under the environment of AVC (Automatic Voltage Control), this paper proposes a new idea about solving the power system dynamic reactive power optimization problem to coordinate with and adaptation of AVC, with the analysis of effect and mechanism of reactive power source and load. And based on the idea, it gives a practical solution method of reactive power optimization between the dynamic and static...
This paper proposes an interleaved buck-boost converter with a single-capacitor turn-off snubber to reduce the switching loss at turn-off transition and to limit rising rate of voltages across switches for reducing spike voltage. In addition, the proposed converter adopts coupled inductor to attain a high step-up voltage ratio and operates in an interleaved fashion to reduce output current ripple...
This paper proposes an interleaved flyback converter with a novel L-C-D snubber to reduce turn-on and turn-off losses. The proposed L-C-D snubber is composed of a single capacitor to form turn-off snubber, and an inductor and a diode connected in parallel to form turn-on snubber. In this circuit structure, the turn-off snubber is used to limit rising rate of drain-source voltage of MOSFET and to reduce...
