FAST LEARNING POWER SUPPLY SYSTEM FOR INDUCTION HEATING PLANT Russian patent published in 2023 - IPC H02M7/217 H05B6/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to devices for converting alternating current into direct current using exclusively semiconductor components connected in a bridge circuit, and can be used in induction heating installations, as well as other power plants that require energy supply from current sources regulated in wide ranges with a small delay of its formation. The technical result is an increase in energy efficiency and electromagnetic compatibility of the electrical complex of an induction heating installation, an increase in the speed of the formation of the supply current level. The power supply system contains a meter for phase currents and voltages, phase-linear voltage transformations, a block for phase-linear current transformations, a block for calculating voltage amplitudes, a block for calculating current reference signals, a block for calculating tasks for consumed currents, a block for calculating deviations of consumed currents, a block of hysteresis controllers, switching combination selection unit, current source break protection unit, controlled rectifier, mains three-phase choke, capacitor unit, DC choke, choke discharge circuit, induction heating unit inverter, resonant circuit capacitor, inductor, induction heating unit control system.

EFFECT: power supply system additionally contains a block for calculating the root-mean-square value of phase currents, a block for determining the amount of consumed current, and a block for intelligent correction of instantaneous consumed current functions.
