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

The method of controlling power transmission to a load permits: to eliminate over-voltage in an electric circuit; to decrease energy losses and time of charging of an energy storing device; to increase service life of switches and provide very high reliability of power transmission to a load. The conception is following: controlling power transmission to a load from additional circuit so that current can be transferred from additional circuit to operating circuit (circuit with a load) and vice versa from operating circuit to additional circuit without interruption (without switching off) circuit of the load.
