METHOD FOR REMOTE WIRE POWER SUPPLY OF FACILITIES Russian patent published in 2016 - IPC B64F3/02 H02J1/04 H02J1/06 H02M7/757 

FIELD: electricity.

SUBSTANCE: in a method for the remote wire power supply of facilities industrial voltage is rectified and via a DC controlled converter is supplied to an input of a power switching bridge loaded to an LC-gyrator that forms high-frequency power signal supplied to an input of the wire line. An output of the wire line is connected to an input of the LC-gyrator, which in its turn, is connected to a high-frequency voltage rectifier, which load is the supplied facility. By means of the LC-gyrator of the switching bridge operating current of the bridge power transformers is limited; output resistance of the high-frequency voltage generator is matched to wave the impedance of the wire line simultaneously changing the amplitude of the output voltage coming to the line. Additionally the coincidence of reactance for matched elements is ensured, at that cosφ in the line is close to one. The input of the remote LC-gyrator is coupled to the output of the wire line while an output of the gyrator - to the high-frequency voltage rectifier, at that the LC-gyrator matches the wave impedance of the wire line with an input resistance of the high-frequency voltage rectifier. According to a current doubling circuit the high-frequency voltage rectifier is supplemented with a capacitor connecting doubling chokes and providing current resonance in the idle mode in order to receive the monotonous growth of an active component of the rectifier input resistance at a reduced power, which is consumed from the power rectifier in order to maintain a permanent voltage value at the load. The output rectifier is connected additionally to a reference voltage comparison circuit, which generates a control signal of deviation that is transmitted via a fibreglass or wire line to the control unit of the high-frequency voltage generator.

EFFECT: reduced weigh and overall dimensions, improved reliability and increased total efficiency factor.
