A pulsed power generator, Pawn, has been assembled at the Naval Research Laboratory. It employees inductive energy storage and opening switch power conditioning techniques with high energy density capacitors as the primary energy store. The energy stored in the capacitor bank is transferred to a vacuum inductor in "'15 ps. Wire fuses provide the first stage of pulse compression. Futiher power c...

This paper proposes a new converter topology that interfaces four ports: two sources, one bi-directional storage port and one isolated load port. In order to improve the efficiency of energy conversion, a sot switching boost converter using a simple auxiliary resonant circuit(SARC) which is composed of an auxiliary switch, a diode, a resonant inductor and a resonant capacitor is adopted. The co...

This paper reviews different types of capacitors and auxiliary source circuit topologies presents an introduction to control strategies used for applications reducing DC-BUS capacitance. The argues in favor replacing bulky electrolytic capacitor-supported power electronic systems with circuits. are widely grid-tied converters (rectifiers) utilized balance, voltage ripple limitation, short-term ...

This paper presents a new control technique to regulate the capacitor voltage in cascaded multilevel inverters. Without requiring transformers, the scheme proposed here allows the use of a single dc power source with the remaining n − 1 dc sources being capacitors. This paper focuses mainly to achieve an effective capacitor voltage regulation with the Phase shift modulation and energy storage u...

-A real time power system simulator has been developed in the Matlab/Simulink environment for testing the prototypes of advanced power system stabilizers and also of the other controllers of new types of energy storage devices such as the Energy Capacitor System composed of electrical double-layer capacitors. The real time transient stability simulations are available on the proposed simulator ...

In this paper, the memory characteristics of two kinds of metal-oxide-semiconductor (MOS) capacitors embedded with Au nanocrytals are investigated: hybrid MOS with nanocrystals (NCs) fabricated by chemical syntheses and rapid thermal annealing (RTA) MOS with NCs fabricated by RTA. For both kinds of devices, the capacitance versus voltage (C–V ) curves clearly indicate the charge storage in the ...

This paper presents super capacitor (SCAP) and battery modeling with an original energy management strategy in a hybrid storage technology. The studied dc power supply is composed of SCAPs and batteries. SCAPs are dimensioned for peak power requirement, and batteries provide the power in steady state. A bidirectional dc/dc converter is used between SCAPs and the dc bus. Batteries are directly c...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...
