Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...

Designing a high-voltage capacitor charger or power supply up to a thousand volts is not a trivial task. A discrete solution using a general-purpose flyback PWM controller with an optocoupler, ...

As the cost to produce supercapacitors (SCAPs, or ultracapacitors) continues to decline, they are carving out a niche in the marketplace between conventional capacitors and batteries. And, although ...

Before Lunar New Year, I had ordered two 3000 F, 2.7 V supercapacitors from China for about $4 each. I don’t actually remember why, but they arrived (unexpectedly) just before the holiday.

Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. C = Q/V = ε A/d = ε0 εr A/d The ability of a capacitor to store maximum ...
