Abstract
Features of current inverter operation are studied. Functional dependence of the duration of half-period (in radians) of the current inverter oscillation process on circuit Q-factor was derived. Performed analytical calculations of inverter current are presented in the graphic form in different systems of coordinates. A new design procedure was developed and new frequency-time characteristics of current inverters were calculated.
