Rfi Filter Questions
What do Electrical Chokes Do?
If you’ve heard the term “electrical chokes”, or read it in a book, you might be confused as to what it means. Is it some kind of medieval torture, or an important component of an electrical circuit? Here’s a simple and thorough explanation of exactly what “electrical chokes” are:
Electrical choke is an old-fashioned term for an inductor (a coil of insulated wire). The choke is wound around a magnetic core and used as a passive indicator. This means the electrical chokes block a higher-frequency operating current (AC) in an electrical circuit, while allowing lower frequency signals to pass through the circuit.
Chokers are used as inductive components in electronic filters. An electronic filter is an electronic circuit that processes signals. Usually, an electronic filter will either remove unwanted frequency components or enhance certain components, or a mixture of both.
Commonly, electrical chokes occur in radio circuits. There are two classes of radio circuits: audio frequencies and radio frequencies. An audio frequency coil (an AF choke) has a ferromagnetic iron core to increase inductance. Chokes for higher frequencies have iron powder or ferrite cores. Instead of a regular patter, they are wound in complex basket winding, as this reduces self-capacitance. At very high frequencies, chokes have non-magnetic cores and a low inductance.
Chokes are used in power supplies. On low-power frequencies they can be an expensive option, but still more efficient than hum filters. With more modern components and circuits, chokes have become obsolete in mains-frequency power supplies. However, you’ll still see high-frequency switch-mode power supplies using small electronic chokes.
Another type of electrical choke is a common-mode choke. Common-mode chokes are useful on a wide range of products, as they prevent electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines. Their ability to pass differential (equal but opposite) currents while blocking the common-mode currents makes them imperative in preventing equipment malfunctions.
And a solid-state electrical choke will handle extremely high currents – much higher than a normal passive inductor.
So there you have it – everything you needed to know about electrical chokes. Not a medieval torture implement after all, but an important part of modern electronics.
