FIELD: electricity.
SUBSTANCE: system comprises transmitting inductance coil; receiving inductance coil separated in space with transmitting inductance coil; half-bridge inverting circuit or bridge inverting circuit with permanent switching frequency in order to excite current in transmitting inductance coil. The above half-bridge inverting circuit includes two switches or the above bridge inverting circuit includes at least two diagonal pairs of switches. Switches or diagonal pairs of switches are designed to perform alternate switching, and current control in transmitting inductance coil is carried out by change in difference between time intervals in switching state of the above switches.
EFFECT: increased efficiency of power transmission in conditions of variable load or variable input voltage or variable connection between Tx- and Rx-parts.
