A high-frequency resonant power conversion system for transferring power from an oscillator to a load or vice-versa, the system including components with at least one fluctuating parameter and is configured to control the value of a defined variable selected from: a certain current, a certain voltage, a phase difference between a certain voltage and a certain current, and a certain power; the system further including a virtual impedance creation loop which is configured to create a virtual component, the virtual component forming a basis for changing amplitude and a phase of the oscillator, thereby to compensate for a deviation from the controlled variable due to the fluctuations.

A circuit for converting single phase power to three phase power and method of operation that automatically starts upon detection of a demand for three phase power from a three phase load connected to the circuit.

A power transformation system that is constructed and arranged to transform power from one or more primary voltage nodes to a separate secondary voltage node using one or more columns comprised of a plurality of capacitive modules each of which is capable of being either electrically inserted into the column or electrically isolated and electrically bypassed. There is a secondary voltage node, at a non-ground potential, to which a first end of the column is electrically connected. In the two-primary node example there are two high voltage switches, each in series with a reactor; one high-voltage switch adapted to electrically connect a second end of the column to the first primary voltage node and the other high-voltage switch adapted to electrically connect the second end of the column to a second primary node. A controller is adapted to control high voltage switches to connect the capacitances comprising the column sequentially to each primary node so as to transform power, by resonant exchange of energy, between those primary nodes and the secondary node.

Capacitive switching device and method utilizing capacitive methods, switch mechanisms and structure to switch on and off of the transfer of alternating current (AC), pulsed power or signals from input side to an output side. More specifically, the present invention relates to AC or pulse decoupled structure which electrically and electronically provides the means to instantaneously switch on and off the transferring forward of power or signal from input terminal connections to output terminal connections. By controlling electrostatic charges to migrate, or not to migrate from its input electrodes to its output electrodes, power or signal transfer forward is controlled.
