A High-Voltage Electrolytic Capacitor Bank

Study And Characterisation Of Electrolytic Capacitor-Bank And Ultra Capacitor Energy Source In DSTATCOM

This paper discusses the dynamic performance and the modeling of a DSTATCOM with Capacitor Bank (CB) and Ultra Capacitor Energy Storage (UCES) considering their equivalent series resistance for improving the operation of power quality in power distribution system. The proposed integrated DSTATCOM system is studied for riding through voltage sags and dynamically controlling active power independ...

Realization of a Smart Electrolytic Capacitor Circuit

Thermal instability of electrolytic capacitor bank used for gas puff valve

It is shown that self-heating of electrolytic capacitors causes the output current of a capacitor bank to increase with successive shots even though the charge voltage is held constant. Self heating of only 10 °C can cause a near tripling in the gas output of the gas puffing valves commonly used in spheromak research. By using metallized polypropylene film capacitors instead of electrolytic cap...

A Merged-Stage High Efficiency High Power Factor HB-LED Converter without Electrolytic Capacitor

This paper introduces a merged converter topology for supplying high-brightness light-emitting diodes for lighting applications. The converter combines a boost-based power factor correction rectifier (PFC) and a resonant converter in a single-stage. In this topology both converters share the same switching components and a bulky electrolytic capacitor, existing in conventional systems, is repla...

Low-Voltage High-Speed Switched-Capacitor Circuits Without Voltage Bootstrapper

Low-voltage high-speed switched-capacitor (SC) circuit design without using voltage bootstrapper is presented. The basic building block used for low-voltage SC circuit design is the auto-zeroed integrator (AZI), which can work at both low voltage and high sampling frequency. With this method, two low-voltage SC systems were successfully designed and implemented in 1.2m CMOS technology. The firs...
