Voltage Controlled Capacitor Ð Feasibility Demonstration in Dc-Dc Converters - 2017 PROJECT TITLE :Voltage Controlled Capacitor Ð Feasibility Demonstration in Dc-Dc Converters - 2017ABSTRACT:This letter presents a voltage-controlled capacitor that varies from 20percent to 100percent of the rated capacitance (one µF) with a control voltage from [*fr1] of the voltage rating to 0 V. Capacitance, self-resonant frequency, and equivalent series resistance were measured with respect to the control voltage. An equivalent circuit and a nonlinear model derived from relationship between permittivity and electrical field were created and implemented in SPICE. A buck converter with input of twelve V, output of 5 V, and switching frequency of five hundred kHz was built to demonstrate the change from 85percent to 40% of the rated capacitance of the voltage-controlled capacitor. The error between the simulation and experiment was limited within tenp.c, which verifies the model. Did you like this research project? To get this research project Guidelines, Training and Code...
