Design Considerations for a Bidirectional DC/DC Converter
With the wide use of energy storage devices such as batteries and supercapacitors, the current trend is to simplify battery charge and discharge management. A bidirectional DC/DC converter can accomplish this to maintain a healthy battery and extend battery runtime. The bidirectional converter uses one powertrain to implement the charge
Flyback Transformer Guide – iNRCORE
A flyback transformer is a coupled inductor with a gapped core. During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gape of the core. It is then transferred to the secondary winding to provide energy to the load. Flyback transformers are used to provide voltage transformation and circuit

Magnetic Fields and Inductance | Inductors | Electronics Textbook
The ability of an inductor to store energy in the form of a magnetic field (and consequently to oppose changes in current) is called inductance. It is measured in the unit of the Henry (H). Inductors used to be commonly known by another term: choke. In high-power applications, they are sometimes referred to as reactors.
How do inductors store and discharge energy?
A current creates an induced magnetic field along the axis of a coil, and you may remember from E&M that energy is stored in a magnetic field according to, where the integral is over space. When the current is maximum, the stored energy in the coil is maximum. Energy is released from the inductor as the current through it decreases.

Inductor Charging and Discharging | Forum for Electronics
Regards, hrerocker. Direction of charging current and discharging current will be different. Charged inductor having stored energy (1/2LI²), it will discharge when there is a path for reveres current flow. If there is no such path, the energy will drop gradually due to magnetic flux. While charging, the current flow suppose right to left.

Toward tiny, solar-powered sensors | MIT Energy Initiative
When a current passes through an inductor, it generates a magnetic field, which in turn resists any change in the current. Throwing switches in the inductor''s path causes it to alternately charge and discharge, so that the current flowing through it continuously ramps up and then drops back down to zero. Keeping a lid on the current

When exactly does this inductor start to discharge?
Recall that an inductor is charging (i.e. the current is increasing) when it sees a positive voltage across its terminals, and the inductor is discharging (current is decreasing) if it sees a negative voltage across its terminals. When the MOSFET is on, the inductor is connected to the positive supply on one side and ground on the other—that

Derivation of Discharging Current of an Inductor
1. Consider the following circuit: When t > 0 t > 0, the inductor L L begins to discharge. I already know from KVL that the sum of voltage drops in the loop containing the inductor is: Ldi(t) dt + Ri(t) = 0 L d i ( t) d t + R i ( t) = 0. From this, how could I derive the equation for the discharged current across the inductor i.e. at any time t t:

Release of energy stored in Inductor and Capacitor
Inductors store energy in the magnetic field generated when current passes through them. When the supply is removed, the collapsing magnetic field induces a current flow in the same direction that it was traveling when it generated the magnetic field in the first place. This is why it is used as one of the storage devices in switching power
