Trinchuk D. An increase of energy conversion efficiency in nonlinear electric circuits with time varying load

The thesis is devoted to an actual scientific task of an increase of energy conversion efficiency in nonlinear electric circuits with time varying load with an example of the electric circuit of electric scooter by the means of improvement of its structure and method of power supply parameters calculating. Designed mathematical model considers nonlinear elements of the electric circuit and time varying load, providing the means for the circuit research. The model's adequacy is experimentally proved. In order to achieve minimal energy consumption during the work on time varying load of the urban driving cycle specific rational value of the supercapacitor capacitance should be applied for electric circuits with both high voltage and low voltage power supply. The improved method of an increase of electric circuit energy efficiency by the means of choosing rational power supply structure provides possibilities of a decrease of energy consumption and does not require additional elements to be included to the circuit.
