Similar to standard wireless charging,magnet chargersallow an electric device to charge when placed on a charging pad but with the help of magnets. Inductive charging with magnets is used in smartphones. The smartphone has several small magnets placed inside it and a coil inductor charged wireless...
I have in mind a new approach, call it "Betwixtodyne" which works in theory but to my knowledge has never been built. It allows continuous tuning with tracking of the regeneration point. It makes the regeneration control a bandwidth control instead with the option to go 'negative bandwidth' ...
This leads to the conclusion that the application requires a step-up DC/DC converter to properly drive the WLED from a single Li-ion cell with an output of 3 to 4.2 V. However, this is not necessarily the case. Take, for example, a 5-mA WLED-current application. The curve in Figure...
VRMs come in two flavors: single-stage and multistage (sometimes called a multiphase VRM). The circuit diagram for a typical single-stage VRM is shown below. The low-side MOSFET and the inductor provide feedback for regulation, and the voltage seen by the processor is stabilized by the capac...
- After the DC power supply is turned on, Q11 and Q14 are turned on, and the current flows out of the positive terminal of the power supply, passes through the inductor L and the primary coil of the transformer, and returns to the negative terminal of the power supply. ...
a) Explain why increasing the number of coils in an inductor increases the inductance. b) Explain what would happen to the inductance if the diameter of the coil was increased. Why does Arc Lights and Vacuum Tubes does not obey ohm's ...
Inductance (XL).The amount of impedance that can occur when an AC charge generates an electromagnetic field (EMF) that opposes the current. A component such as an inductor is often used to generate inductance. Capacitance (XC).The amount of electrical charge stored in the circuit. A component...
