Biletsky O. Energy processes in charge circuits of supercapacitors with variable initial voltages

The dissertation is devoted to the development of the theory of energy processes in the circuits of supercapacitors' charge from voltage sources such as batteries based on consideration of capacity depending on voltage capacitors and purposeful changing the initial and the final voltages of their charge for increasing the energy efficiency of the combined power sources. A new criteria was developed for evaluating the energy efficiency of electrical circuits of aperiodic and an oscillatory charge of the supercapacitors from constant voltage source, that take into account changing the initial and the final voltages and the capacitance of supercapacitors during the charging cycles. For the first time there were established patterns of reduction of electricity losses in the circuits of charge of supercapacitor from the battery and increase the coefficient of energy transfer with increasing initial and final voltage on the terminals of the nonlinear capacitor and the Q factor of the circuit of charge. A new method of parametric synthesis of the circuits of charge the supercapacitors from batteries by solving the inverse problem was developed, i.e. determining the initial voltage on the terminals of the supercapacitors, which provides maximum coefficient of energy transfer from the battery charger at a given Q factor of the circuit of charge.
