CONTROL DEVICE FOR FLYBACK CONVERTER Russian patent published in 2014 - IPC H02M7/00 H02M7/48 

FIELD: electricity.

SUBSTANCE: device contains a transformer for the insulated voltage flyback converter, a diode, a secondary circuit with load and a switching element, at that one output of the switching element is connected to anode of the first diode while its cathode is connected to the summator input and to one input of the primary transformer winding, by the other input this winding is connected to the power supply bus; the second output of the switching element is coupled to the common bus at the side of the transformer primary winding; the third output of the switching element is coupled to the control device output; secondary winding though the secondary circuit is connected to the load; the summator is connected to the power supply bus by its one input and to the output of the controlled signal source by its other input, while its output is connected to the input of a measuring instrument; the measuring instrument has two input coupled to the tripping pulse generator; he tripping pulse generator is connected to the control device input.

EFFECT: universality of device, potential use of any voltage flyback converter with control device during operation with insignificant capacity of the load or operation with high-intensive loads leading to significant excess of output current without use of specialised control devices.
