I have a Sears deep-cycle lead-acid 12v battery already which I've only used once or twice a year for certain power applications. I was thinking of purchasing an identical model and wiring it in ...

This state-of-the-art synchronous buck-boost converter operates in either buck mode or boost mode, which enables high efficiency over wide input voltage range. The parallel of MOSFETs along with ...

There are still a lot of hand-held tools in use with Ni-Cd or Ni-MH batteries. The simple charger has no switch-off criteria, and you need to measure and adjust the charge time, else you will badly ...

Typically, a power supply is comprised of a power transformer, which is then followed by a conventional bridge rectifier. The bridge rectifier is constructed using four diodes that are interconnected ...

This charge-pump circuit, using just a few diodes and capacitors, ups the input voltage by a factor of 1.5 in contrast to the usual voltage-doubling output. Micropower product designs sometimes ...
