METHOD AND SYSTEM FOR CONTROLLING REVERSAL CONVERTER OF CONSTANT VOLTAGE IN PERMANENT VEHICLE Russian patent published in 2019 - IPC H02J7/14 H02M3/04 H02P11/04 

FIELD: motor vehicle industry.

SUBSTANCE: group of inventions relates to electrical systems of vehicles. Method of controlling a reversible converter constant voltage in a permanent vehicle involves the following. Deflection between the specified power value and estimated value of power on the transducer terminals is determined. Preset value of voltage is determined at transducer terminals depending on certain deviation and allowable value of specified deviation so that preset value of voltage could be determined when flowing current at converter terminals is zero. Note here that said motor vehicle comprises power plant including internal combustion engine mechanically connected with electric machine powered by inverter. Inverter is electrically connected to the battery through a reversible converter constant voltage in a permanent. Converter is also connected to auxiliary devices. Invention covers also the control system of reversible converter constant voltage in a permanent vehicle involves.

EFFECT: improved accuracy of converter control.
