Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Abstract: The cascaded H-bridge low-capacitance static compensator (StatCom) deliberately reduces the capacitor size while allowing large oscillations in capacitor voltages. When a capacitor ...

Abstract: Switched-capacitor DC-DC converters are suitable for on-chip power circuits. Hysteresis control with a high bandwidth comparator can achieve high efficiency over a wide load range and ...
