Electrical ballast
For simple, low-powered loads such as a neon lamp, a fixed resistor is commonly used cause the resistance of the ballast resistor is large it determines the current in the circuit, even in the …
Chokes Explained
Why use a choke? Why not just a big series resistor? A choke is used in place of a series resistor because the choke allows better filtering (less residual AC ripple on the supply, which means …
What Does a Capacitor Do | Explanation | Albert Swag
In the capacitance formula, C represents the capacitance of the capacitor, and varepsilon represents the permittivity of the material. A and d represent the area of the …
Intro to Electronic Components: Inductors and Chokes
Chokes are a specific type of inductor, are specifically used to block high-frequency AC signals while allowing low-frequency DC signals to pass. Chokes are most …
What is Choke Filter?
Definition: Choke filter consists of an inductor connected in series with rectifier output circuit and a capacitor connected in parallel with the load resistor. It is also called L-section filter because …
Why an Electronic Choke Circuit Diagram is Important
The choke functions through resisting current changes that flow through it. This helps in the smoothening out of all DC output voltage variations. Particularly, this is very useful for any power supply used in supplying power to the electronic …
How Choke (Electronics) Work – Type, Principle, Parts, Application
What is the function of the choke or ballast? An inductor, usually a choke, is very common in line frequency ballasts to provide the proper starting and running electrical conditions to power a …
What is Choke Filter?
Definition: Choke filter consists of an inductor connected in series with rectifier output circuit and a capacitor connected in parallel with the load resistor. It is …

Guide to Ceramic Capacitor Dielectrics and Other Types Capacitor electrical behavior is determined, in part, by the capacitor dielectric. Learn all about capacitor dielectrics …
Choke Input Filter Operation
The below Fig. shows a typical choke input filter circuit. It consists of a Choke L connected in series with the rectifier output and a filter capacitor C across the load. Only a single filter section is shown, but several …
Comprehensive Guide to Chokes in Power Applications
Filter chokes with matching capacitors, tuned to filter certain frequencies, or for (passive) compensation of reactive power loads. Current-compensated Chokes: These filter chokes …
How Choke (Electronics) Work – Type, Principle, Parts, …
What is the function of the choke or ballast? An inductor, usually a choke, is very common in line frequency ballasts to provide the proper starting and running electrical conditions to power a fluorescent lamp or HID lamp.
Reactors in a Power System
A choke, also known as a line choke, is a reactor that is used to limit current to AC or DC drives in the event of short circuits inside the drive. When large short-circuit currents …
Common Mode Filter Design Guide
low pass common mode filter, a common mode choke is the reactive element employed. The value of inductance required of the choke is simply the load in Ohms divided by the radian …
The complete guide to ballasts for fluorescent lights
A magnetic ballast (also called a choke) contains a coil of copper wire. The magnetic field produced by the wire traps most of the current so only the right amount gets through to the …
Choke (electronics)
In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually …
Intro to Electronic Components: Inductors and Chokes
Chokes are a specific type of inductor, are specifically used to block high-frequency AC signals while allowing low-frequency DC signals to pass. Chokes are most commonly found in electronic filters and when combined …
Choke Input Filter Operation
The below Fig. shows a typical choke input filter circuit. It consists of a Choke L connected in series with the rectifier output and a filter capacitor C across the load. Only a …
How does it Work? Common Mode Chokes
the common mode signal that enters or leaves a PCB. X and Y capacitors are commonly used to shunt the common mode noise away from the circuits of interest, while a common mode choke …
Power Factor Correction (PFC) Explained | Article | MPS
The problem with the current in the capacitor is that it looks very similar to a delta function. This type of wave is, ideally, an infinitely short, infinitely powerful pulse. A wave of this shape is …
CHOKES
Chokes are fixed inductors primarily intended to "choke" off alternating currents, including rf from DC supply lines. The "rf choke" is designed to have a high impedance over a large range of …
