Phase Angle Control in a Series RLC Circuit Using an Electronically Switched Capacitor
Keywords:
switched capacitor, phase angle controlAbstract
In this article, the principle of the switched capacitor in a series RLC circuit is presented. The classical methods for phase angle control are described, and a novel control method, where the capacitor is placed in the center of a bidirectional H bridge switch. Using an electronic circuit simulation program, the representative voltage and current curves are obtained. The phase angle at various transistor switching frequencies is determined. Also, a study of the capacitor value and the switching frequency on the duty ratio resolution and phase angle is performed. The experimental results confirm the data acquired from computer analysis.Downloads
