AC and DC Windings: Understanding the Difference

AI Thread Summary
AC windings and DC windings refer to the types of electrical windings used in transformers and other devices, where AC windings are designed for alternating current and DC windings are tailored for direct current applications. The primary difference lies in their operational characteristics; AC windings facilitate the transformation of voltage levels in AC systems, while DC windings are often used for biasing in specific applications, such as in fluxgate magnetometers. In these magnetometers, a DC winding can help cancel out a DC magnetic field to ensure accurate measurements. The discussion highlights the practical applications of both winding types, particularly in the context of magnetic field measurement. Understanding these differences is crucial for selecting the appropriate winding type for specific electrical applications.

what is meaning of ac winding and dc winding?how it differs from each other?
advanced thanks.
 
Engineering news on Phys.org
In what context are you seeing these terms?
 
A standard fluxgate magnetometer for measuring dc magnetic fields uses a dc winding (biasing current) on an ac transformer to cancel the imposed dc magnetic field and null the output signal. Sometimes the dc bias current is imposed directly on the ac secondary output coil, as shown in the thumbnail.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
