摘要： A family of power converters has input ac voltage regulation instead of output dc voltage regulation. The bi-directional converters control power flows and maintain the input ac voltage at or close to a certain reference value. These bi-directional power converters handle both active and reactive power while maintaining the input ac voltage within a small tolerance. Use of these converters is favorable for future power grid maintenance in that they (i) ensure the load demand follows power generation and (ii) provide distributed stability support for the power grid. The converters can be used in future smart loads that help stabilize the power grid.

摘要： A method for identifying impedance related parameters in a wireless power transfer (WPT) system including n coils is disclosed. Said method includes determining optimum values of the impedance related parameters based on a set of measured input impedance by applying an evolutionary algorithm to solve optimum solutions. Wherein the set of measured input impedance includes an input impedance vector {right arrow over (Z)}=(Z1, Z2, . . . , Zm-1, Zm), each input impedance in the vector (Zk) measured at different frequencies fk, (k=1, 2, . . . m); and the impedance related parameters includes dll+1 representing a distance between the l-th coil and the l+1 coil (l=1, 2, . . . n−1) and Ci representing a capacitance of the capacitor connected to the i-th coil (i=1, 2, . . . n).

摘要： A high-frequency ac-dc power converter takes an input ac signal and converts it to an output dc signal. The converter has at least two front-end rectifier diodes arranged as a full wave rectifier of the input ac signal. A first inductor positioned at the output of the full wave rectifier. An output capacitor is connected across a load for the converter. There are at least one additional inductor and one additional capacitor. A switching circuit selectively forms different (LC) resonant circuits with the inductors and capacitors during a cycle of the input ac signal to form a dc-dc power converter.
