This Design Idea describes a method for adding a low-end ADC to a single programmable-logic I/O pin. The circuit charges a capacitor through a resistor while measuring the time to charge the capacitor ...

Combining the unique strengths of lithium batteries with crazy-fast charging, carbon ultra-capacitors could save a ton of weight and add significant range and power to electric vehicles, according ...

Instead, it uses diodes or other switching elements to transfer charge between capacitors in stages. Each stage will effectively increase the voltage by the supply voltage — in theory.

The charging circuit here uses an ATtiny13A and a MP18021 half-bridge gate driver to charge the capacitor, and also is programmed in a way that allows for three steps for charging the capacitor.

Fast-charging super-capacitor technology Date: May 14, 2020 Source: University of Surrey Summary: Experts believe their dream of clean energy storage is a step closer after they unveiled their ...

The classical flyback capacitor charger operates in CCM (continuous-conduction mode). Flat-topped, short-duration current pulses on the transformer’s secondary charge the storage capacitors (Reference ...

Experts from the University of Surrey believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and ...

A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...
