Based on buck, boost or buck-boost topologies, which are well known in dc–dc converters, these inverters use dc inductors for energy storage or high-frequency transformers for both energy storage and electrical isolation as required for safety reasons.

Figure 1 shows two examples of pulse forming line using inductive energy storage, both circuits consist of an initial energy storage capacitor, a switch (MOSFET), and a transmission line (PFL).
Let''''s consider a quick example of how an inductor stores energy in an SMPS. Closing the switch for a switched mode power supply increases the current flowing to the load and allows energy to store in the inductor. Opening the switch disconnects the output of the supply from the input.
Because capacitors and inductors can absorb and release energy, they can be useful in processing signals that vary in time. For example, they are invaluable in filtering and modifying signals with various time-dependent properties.

Energy Stored in an Inductor Key Takeaways Understanding the energy stored in an inductor is crucial for various electrical and electronic applications, including power supplies, transformers, and energy storage systems. Inductors play a vital role in regulating current flow, filtering signals, and managing energy transfer in circuits.
In conclusion, the inductor energy storage equation is a fundamental concept in understanding the behavior and application of inductors in electrical circuits. It provides a basis for designing and analyzing circuits involving inductors, ensuring optimal performance in various applications.
WL = 1 J So, the energy stored in the inductor’s magnetic field is 1 joule (J). This example demonstrates the application of the inductor energy storage equation in calculating the energy stored in an inductor’s magnetic field for a given inductance and current.
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.
Recall the inductor energy storage equation: WL = (1/2) * L * I2 Given the values: We can now calculate the energy stored in the inductor: WL = (1/2) * 0.5 H * (2 A)2 WL = (1/2) * 0.5 H * 4 A2 WL = 1 J So, the energy stored in the inductor’s magnetic field is 1 joule (J).
While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well. See Linear Technology’s Application Note 77 for complete details.
