Decoupling capacitors - can control high-frequency noise, removing voltage ripples from the power supply. Energy storage and supply - deliver stored energy bursts quickly, like a camera flash for example. Signal filtering - they are able to block low-frequency signals and allow higher-frequencies to pass through. Useful in telecommunications.
A capacitor is a device used to store energy as an electric charge, similar to a battery but they are able to release the charge much faster. The amount it's able to store is known as capacitance, this is measured in Farads (F). They comprise 2 metal plates (conductors) separated by an electrical insulator (dielectric).
the proposed flying capacitor LLC (FCLLC) solution with advantages of each. The FCLLC comprises a step-down resonant switched-capacitor (ReSC) stage followed by a resonant transformer-based stage which provides soft charging of the flying capacitors, galvanic isolation, and an additional step-down through the transformer.
One such evolutionary branch of power converters is hybrid switched-capacitor (SC) converters which leverage capacitors as highly energy-dense components, high figure-of-merit switching devices, and small magnetics to realize high-performance power electronics. To fully exploit the benefits of this relatively new class of power converters

impedances of the inductor and capacitor cancel out and the total impedance only reflects resistive components of the impedance of the components.19 The resonance frequency can be additionally tuned by adding more reactive elements to the driving scheme such as a capacitor C p in parallel with the device.

Part Name: Electrolytic and Ceramic Capacitors, Varying Capacitance Part Description: A capacitor is fundamental passive electronic device that is used to control the capacitance (rate of change of electric charge over corresponding change in potential voltage) of a given part of a circuit. In essence, a capacitor is an energy storage device and the capacitance []
First, we investigate negative capacitance in an isolated ferroelectric capacitor, and show that the negative capacitance states can be directly observed during switching. Careful analysis of the switching dynamics and phase-field modeling show that the signature of negative capacitance arises from the accelerating growth of domain walls, when an increasing volume
This thesis presents a control technique to improve power density and efficiency of a specific power converter topology, the flying capacitor multi-level (FCML) topology. Controlling these converters in such a way to achieve zero-voltage switching (ZVS) across the full range of duty cycles, reduces switching losses and therefore can be used to allow for more
