How are inductors used in switched mode power supply?
Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the “off” switching periods and enables topographies where the output voltage is higher than the input voltage.
What causes the voltage across an inductor to change?
Any change in the current through an inductor creates a changing flux, inducing a voltage across the inductor. By Faraday’s law of induction, the voltage induced by any change in magnetic flux through the circuit is given by
Which is a voltage source inverter ( VSI )?
A voltage source inverter (VSI), which is illustrated Fig. 5.33 and current source inverters (CSIs) with different waveforms such as a square wave, pulse width modulation (PWM), and so on are used in the industry.
What is the circuit of a Z source inverter?
Circuit of the Z-source inverter. It employs a unique impedance network coupled between the power source and the converter circuit that consists of a split inductors L1 and L2 and capacitors C1 and C2 connected in X shape.
How are inductors used in alternating current equipment?
Inductors are widely used in alternating current (AC) electronic equipment, particularly in radio equipment. They are used to block AC while allowing DC to pass; inductors designed for this purpose are called chokes.
Why is a potential difference induced on a change in current in an inductor?
One intuitive explanation as to why a potential difference is induced on a change of current in an inductor goes as follows: When there is a change in current through an inductor there is a change in the strength of the magnetic field. For example, if the current is increased, the magnetic field increases.
Why are shielded inductors used in power regulation systems?
Shielded inductors. Inductors used in power regulation systems, lighting, and other systems that require low-noise operating conditions, are often partially or fully shielded. In telecommunication circuits employing induction coils and repeating transformers shielding of inductors in close proximity reduces circuit cross-talk. Types
