23.12: Inductance
Mutual inductance is the effect of Faraday''s law of induction for one device upon another, such as the primary coil in transmitting energy to the secondary in a transformer. See Figure, where simple coils induce emfs in one another. Figure 23.12.1 23.12. 1: These coils can induce emfs in one another like an inefficient transformer.
Energy Storage Using Supercapacitors: How Big is Big Enough?
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.

Energy Stored in an Inductor | Electrical Academia
Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up ...

Inductor i-v equation in action (article) | Khan Academy
equation: v = L d i d t i = 1 L ∫ 0 T v d t + i 0. We create simple circuits by connecting an inductor to a current source, a voltage source, and a switch. We learn why an inductor acts like a short circuit if its current is constant. We learn why the current in an inductor cannot change instantaneously.

How to make a boost converter circuit
3. The simplest solution would be to use a small, integrated boost IC. For example here is one from TI, but there are lots of other choices from other vendors as well (The component value choices are clearly explained in the datasheet): TPS61046. However, you mention you need 2V above your 5V rail to switch your FET.
A single inductor tri-input dual-output buck-boost DC-DC converter with MPPT for multi-source energy harvesting …
Energy harvesting is an attractive technique of getting energy from environment and extending battery lifetime for remote wireless sensor networks (WSN), wearable biomedical electronics, and internet of things (IoT). In such a system, it delivers all harvested energy directly to the load with surplus energy recycled in the battery. Accordingly, power …
Boost converter, how does diode allow current from inductor to flow towards capacitor?
For a certain period called Duty Cycle the inductor is gonna charge up with the increasing current that flows through it, and like that it will store energy. As the FET is turned off, the current would normally decrease, but, as there´s a inductor it will try to force the current to same direction it was flowing due to Lenz´s Law.
switch mode power supply
Overly simple explanation alert!! In very simplistic terms, a boost converter circuit looks like this: - To the left is the power source (48 volts) and to the right is your load. In between is a switch (usually a MOSFET) that "shorts" the inductor to 0V for a …
The Benefits of the Coupled Inductor Technology | Analog Devices
The big benefit, however, is that a 50nH inductor will have > 4x better transient performance than 210nH, This benefit usually enables you to eliminate the big, unreliable, expensive, and bulkly output capacitance completely. Only the high-performance ceramic capacitors, the ones that are already present, remain.
Inductor Current in a Boost Converter: a SPICE Analysis
Energy storage over time for the boost converter''s inductor. TIP: LTspice will automatically generate a power plot like this if you hold down the ALT key while clicking on the relevant component. Now we''ll use LTspice to display absolute value so that the positive and negative energy don''t cancel each other out (Figure 6).

Boost inductor L1 discharges, meanwhile giving energy to load. When MOS S1 turns on, Boost inductor is charged, and diode D1 is off. The output capacitor discharges and transfers energy to load. Line frequency diode D3 returns the current from output to
How to make a boost converter circuit
The energy stored is 1/2*L*I^2. Then when the switch turns off the inductor ramps down, though at this point the voltage across the inductor is in the opposite direction and equal to Vout-Vin. So the inductor provides energy to the output during the off time
How to Select Inductor for Boost Converter | ElectronicsBeliever
The 75% maximum stress will do. 1. Select Inductance Value a. Define the switching frequency for the boost converter Example: Fsw = 300kHz b. Define the input and output voltage Example: Vin = 12V, Vout = 24V c. Determine the duty cycle Dutycycle = 1 – (Vin / Vout) Example: Dutycycle = 1 – (Vin / Vout) = 1 – (12V.

Choosing inductor and capacitor for boost converter
At least for an inductor of 2.2 µA, trying to get 1.3 A out of it would be a bad idea: You need a more powerful boost converter, like the TPS61021A: And putting your requirements (1.6–3.1 V, 3.3 V, 1.3 A) into TI''s Webench tool indeed results in a design based on the TPS61021A, with a 1 µH inductor (SRU1028-1R0Y), and 10/30 µF capacitors:
