The conception (for eliminating all mentioned above problems) is following: controlling power transmission to a load from additional circuit (without interruption current of chosen capacitor(s) and without interruption voltage of chosen alternating current source) 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. Decreasing the time of charging an energy storing devices by choosing a voltage source of alternating current which amplitude exceeds approximately no less than one order of magnitude the rated voltage of said energy storing device. For example, voltage source can be source of alternating current of 120 V, 60 Hz, or source of alternating current of 240 V (60 Hz), or source of alternating current of 220 V (50 Hz), or source of alternating current of 380 V (50 Hz). Technical solutions realizing said conception permit interrupting current of a load without interrupting circuit of power transmission to the load.

The using of conception will improve power Power Factor, because the current is capacitive current.

This conception can control power transmission to a load with a rated voltage, by choosing capacitor(s) [with appropriate capacitance(s)] permitting to obtain desirable rated current of said load (when current is equal to rated current I_RAT, the voltage is equal to rated voltage U_RA of the load).
