METHOD FOR CONTROLLING CURRENT INVERTER Russian patent published in 2006 - IPC H02M7/521 

FIELD: transforming equipment engineering, possible use in systems for controlling inductive heating machines.

SUBSTANCE: method for controlling current inverter includes generation and one by one injection of control impulses to pairs of rectifying cells, related to anode and cathode groups, forming direct and reverse semi-waves of voltage. Instantaneous values of voltage is measured on load. Level of voltage is set. Measured instantaneous value of voltage on load is compared to given voltage level. If measured instantaneous value of voltage exceeds given level of voltage, in the moment of such excess additionally formed are control impulses which are injected into all rectifying cells of anode or cathode group.

EFFECT: increased reliability of current inverter operation.
