The inductive voltage divider is a type of voltage divider circuit. It works by using the properties of inductors to divide the input voltage applied to the circuit into two output voltages, one at each terminal of the coil.
The inductive voltage divider exhibits high impedance unless there is a change in current through it, which means that it will not cause significant power dissipation when there is no load connected to either output.
An inductive voltage divider is one of the most common ways of generating an AC voltage from a DC voltage source. This circuit uses the principle of electromagnetic induction to generate an alternating voltage when fed by direct current.
This is done by passing DC through an inductor, which creates an electromagnetic field when operating. The resulting current in the secondary winding causes a back-EMF in the opposite direction, creating an alternating current output that corresponds to the input frequency of the input signal.
History Of Inductive Voltage Divider
Ernst Alexanderson invented the first inductive voltage divider in 1922. He used it to build the first radio broadcast transmitter for General Electric Company (GE). The inductive voltage dividers were initially called “coil meters,” and they were also known by other names such as “inductance dividers” and “voltage dividers.” They were used for measuring voltage and current across coils or antennas of radiotelegraphy transmit
How Inductive Voltage Divider Works
An inductive voltage divider is a device that is placed in series with the electric circuit that provides electrical power to the device. It has two coils of wire connected at one end and connected to the circuit at the other.
The coils are usually wound so as not to interfere with each other. The primary purpose of an inductive voltage divider is to divide voltages by using the resistance of one coil to resist any change in current flow through it, but not both coils.
Inductive Voltage Divider Circuit Diagram
Inductive voltage divider has two terminals where terminal one is input, Vin; terminal two is ground. The output terminal is defined as Vout. L1 and L2 are two inductors.
Inductive Voltage Divider Formula:
L1 and L2 are inductance, measured in henry (H).
Vin is the input voltage, and it is measured in volt (V)
Vout is the output voltage, and it is also measured in volt (V)
Uses Of Inductive Voltage Dividers
An inductive voltage divider is used to provide power to an electric coil. There are several uses for an inductive voltage divider. One of the most common is constructing a radio antenna, which functions as a matching device or “transformer.” The inductor or transformer steps down the power level from the radio transmitter to be radiated by the antenna.
So, What Is Inductive Divider?
An inductive voltage divider (IVD) is one of the many types of voltage dividers. A passive device divides the input voltage at a ratio determined by its inductance and capacitance values.
The IVD has two main areas: an input and an output. The input connects to the circuit where the desired voltage needs to be divided and provides a high-level current and low-level voltage.
The output then takes this current/voltage and passes it through a passive series of coils, which will divide it by different ratios depending on their inductance and capacitance.
