Sometimes it is desired to power a circuit from a battery where the required supply voltage lies within the discharge curve of the battery. If the battery is new, the circuit receives a higher voltage ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

White LEDs are usually driven with a constant DC current source in order to maintain constant luminosity. In portable applications with single-cell Li-Ion source, the sum of the voltage drop across ...

Switching power supplies are familiar to Hackaday readers, whether they have a fairly conventional transformer, are a buck, a boost, or a flyback design. There’s nearly always an inductor involved, ...

The Kobe University-developed direct current voltage boost converter has much reduced electromagnetic noise and a high energy efficiency of over 91 percent, which is unprecedented for a MHz drive with ...

VoltScaler improves efficiency and mitigates voltage drops, helping to meet the increased power needs of 5G remote radio heads (RRHs) at the top of cell towers. The boost system features three ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

With potential high density, low cost, and a nature-friendly makeup, zinc-air batteries are touted to be the future of many energy devices. Still, their low voltage of 1.4 V remains a barrier to more ...

“Power Boost” mode can be helpful in a pinch, but it’s only safe for certain appliances and devices. Here are best practices ...
