Abstract

A capacitor, inductor, and power line are arranged in a series parallel combination tank circuit that operates over four quarters of a complete cycle. During the first quarter cycle: power is applied to the tank circuit, current flows through the inductor to the capacitor, current is stored in the inductor, and the capacitor is charged. During the second quarter cycle; current is released from the inductor as the capacitor discharges current to another parallel inductor or resistive load. During a third quarter cycle: current flows in the capacitor from the opposite direction, the capacitor is charged, current pushes out from the capacitor to the incoming power line, and current is stored in the inductor. During the fourth quarter cycle: the capacitor discharges in the opposite direction, current parallel to another inductor or resistive load flows in the opposite direction, and the inductor releases current to incoming power line.
