DEVICE TO CONTROL POWER GENERATOR OUTPUT VOLTAGE Russian patent published in 2012 - IPC H02P9/30 

FIELD: electricity.

SUBSTANCE: power generator (100) comprises a generator winding (103), an excitation winding (104) and a magnetising winding (102). A smoothing capacitor (113) smoothes current generated by the excitation winding (104) and sends this current to the magnetising winding (102). A transistor (110) provides for PDM control so that the output voltage of the generator winding (103) reduces to the preset voltage. There is a diode (112), which locks the reverse flow of the magnetising current. The transistor (10), which is connected in parallel to the diode (112), is controlled as antiphased with the current of transistor (110) control.

EFFECT: unit of porosity control (1) makes a judgment on whether porosity of a transistor control signal exceeds or does not exceed the rated porosity, and when the porosity control unit makes a judgement that porosity of control signals exceeds the rated porosity, the unit increases the period of sending control signals by thinning of control signals.
