Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual tolerance ranges afford. Precision matching of components from parts on hand ...

Abstract: The active capacitor with variable capacitance control is able to actively and variably mimic the voltage–current characteristics of a physical passive capacitor; however, the existing ...

Abstract: This article proposes a three-phase resonant driver based on the resonant switched capacitor (RSC) for the light emitting diode (LED). The employed LED is chip-on-board (COB) based ...
