Features of the energy interchange between capacitors in the circuit using unidirectional commutator or bidirectional one

Processes of electric energy interchange between two capacitors charged to different voltage in a circuit with inductance are studied. It is found that the energy loss in such circuit and a coefficient of energy transfer from one capacitor to another one connected by bidirectional commutator (conducting a current in both directions) are determined only a difference of initial voltages on capacitors and a relationship of their capacitances, and do not depend neither on a ohmic resistance, nor on inductance of circuit. In this case the energy interchange between capacitors proceeds until transient damping. At the same time it is shown that if capacitors are connected by the unidirectional commutator (conducting a current in one direction) and energy interchange between them is an oscillatory process, then the energy loss will decrease, and the coefficient of energy transfer will increase at decrease of a difference of initial voltage of capacitors and with increase of inductance in the circuit. For such energy interchange the dependences of energy loss and coefficient of energy transfer between capacitors on relationship of their capacitances are determined. It is shown that the maximal energy loss takes place at equal capacitances of connected capacitors for any values of inductance in circuit.
