Prior to the ubiquity of LED bulbs, I installed a Lutron dimmable light switch in a bedroom that runs a wall socket. With incandescent bulbs, everything worked great, but when I switched out all of the bulbs for dimmable LEDs (Cree), the bulbs would not turn off all of the way.

A capacitive load is similar to inductive load in terms and voltage and current values do not match each other. But in capacitive load, voltage reaches its peak value faster than current does. Capacitors are used …
A transmission line with termination applied at the load end. A CMOS IC is assumed in this figure. At the load end, the characteristic impedance needs to match the load component''s input impedance, which is derived in the above image. There is a reflection coefficient defined at the interface between the load component and the transmission line.
Matching reactive loads Almost certainly, a matchbox will be asked to match loads with both resistive and reactive parts. Thinking of such a load in its QX1609-MacCluer01 R > 50 Ω Z C L QX1609-MacCluer02 In Out (Vf – Vr) n 50 Ω 1:n toroid Figure 1 — A common L-network matchbox that transforms R to Z.

Adjusting the source impedance or the load impedance, in general, is called "impedance matching". There are three ways to improve an impedance mismatch, all of which are called "impedance matching": • Devices intended to present an apparent load to the source of Zload = Zsource* (complex conjugate matching). Given a source with a fixed voltage a…
The goal is to match the output impedance of a low-power RF transistor amplifier to a 50-output load, and 50 Ω is a universal standard for most receiver, transmitter, and RF circuits. Most power amplifiers have a low output …
3/12/2007 Matching Networks 3/9 Jim Stiles The Univ. of Kansas Dept. of EECS A: NO! We can in fact modify our circuit such that all available source power is delivered to the load—without in any way altering the impedance value of that load! To accomplish this, we must insert a matching network between the source and the load:
Impedance matching to an antenna in a receiver or transmitter is an essential process. Some loads are constant; thus, a single fixed Z-matching circuit can be used.
In electronics, a load is anything connected to a power source that consumes power. If you connect a light bulb to a battery, the light bulb is the load. By the same turn, an antenna system—its radiating elements and feed line—con - nected to a transmitter is a load. It sounds like a simple idea, and to a certain

A capacitive load is similar to inductive load in terms and voltage and current values do not match each other. But in capacitive load, voltage reaches its peak value faster than current does. Capacitors are used in a wide variety of electronic applications, such as radios, televisions, computers and power supplies.
control is larger when the load is very light, which reduces the control eciency. To improve the eciency of DAB at light loads, schol-ars have done a great deal of research. The authors of [26] proposed an enhanced DAB topology that employs an adjustable-tap transformer to extend the ZVS range and improve eciency at light loads.
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
I am currently trying to impedance match a capacitor as a load. In detail, it is an insulating thin film grown on top of a conductive layer (grounded). We now sputtered small Pt electrodes on top and want to apply a voltage to these. We expect the capacitance in the area of 0.5 - 1 pF and our source has a 50 Ohm impedance.
How synchronous buck converters continue to operate in light load conditions. A synchronous buck converter like this will produce the correct voltage irrespective of load current and, even if the load current is quite high, providing the MOSFETs used for the switching are low on-resistance, Vout will remain largely unchanged.
In any HVAC unit, the capacitor must match the motor. The voltage can go higher if necessary but never lower, while the MFD (uf) should always be the same.
