There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

Many electronic devices require user input for setting the application properties. Typical input devices include pushbuttons, potentiometers, and touchscreens. To minimize overall project cost, you ...

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk ...

Part 2 goes further into the methods that can help lower EMI in switched-cap designs, including implementation of active EMI filters and visible light communication. Part 2 delves further into why ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

The batteries we rely on for everything from our cars to our cell phones use a chemical reaction to store and release an electrical charge. The chemicals involved force a large number of tradeoffs in ...

For the cautious, a good piece of advice is to always wait to buy a new product until after the first model year, whether its cars or consumer electronics or any other major purchase. This gives the ...
