Abstract

An influence of variable capacitor topology on maximal-to-minimal capacitance ratio is analyzed. Two types of parallel-plate variable capacitor with electrode overlap area change were considered in the work: fan-shaped and comb-shaped. It was established that when electrode linear dimensions decrease, maximal-to-minimal capacitance ratio increases without change of variable capacitor dimensions. Thereby it is possible to increase energy generators efficiency and their output power.
