Inductors, fundamental components in electrical circuits, possess the remarkable ability to store energy in the form of a magnetic field when an electric current flows through them. This energy storage capability is crucial in various applications, from power supplies to radio transmitters.
The energy, stored within this magnetic field, is released back into the circuit when the current ceases. The energy stored in an inductor can be quantified by the formula \ ( W = \frac {1} {2} L I^ {2} \), where \ ( W \) is the energy in joules, \ ( L \) is the inductance in henries, and \ ( I \) is the current in amperes.
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
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.
Inductors are used in power supplies to filter and stabilize the output voltage. They smooth out fluctuations in the current and maintain a steady voltage by storing and releasing energy as needed. This filtering capability is crucial for ensuring that electronic devices receive a consistent and reliable power supply.
Thus, the inductor takes no more energy, albeit its internal resistance does cause some losses as the current flows through it, such that Plosses= Im2R. These losses are unavoidable because the constant current flow is necessary to maintain the magnetic fields.
