SCHEMES OF POWER SOURCE Russian patent published in 2017 - IPC H02M1/36 H02M3/335 

FIELD: electricity.

SUBSTANCE: converter circuit is shown having a main switching circuit on the primary of the transformer to control the supply of current to the storage coil in the primary winding when the main switching circuit is conductive. The converter circuit comprises: a control circuit operatively connected to the main switching circuit for controlling the main switching circuit, the control circuit comprising a control capacitor configured to include a control circuit and disconnect the main switching circuit; a secondary inductance coil magnetically coupled to the storage coil and configured to run the control circuit for operation and to disconnect the main switching circuit in response to a voltage change on the storage coil when the main switching circuit is conductive; and a charging circuit connected between the auxiliary inductor and the control capacitor and configured to include an auxiliary inductor to charge the control capacitor.

EFFECT: ensuring better stabilisation of the output voltage in the network.
