A High Speed NiCd Charger for Electric R/C - A few years back, I
published a design for a Low Cost Thermal Peak Detection Charger. Since
then, I've designed several other chargers, in my ongoing quest to avoid
having to spend money. Of course, in building all these designs, I've
probably spent more than a really good commercial charger would have cost
me. But designing and building is half the fun... [Stefan Vorketter]
AA Battery Solar Charger (Solorb) - This almost trivial circuit may
be used to charge a pair of AA or AAA sized cells in sun….(added 4/02)
AN2 Portable Ni-Cd Battery Charger: Inexpensive Load Tolerant Step-Up Energy
Source - Zetec Semiconductors Applications Notes A relatively simple low
parts count topology is presented for a one transistor design, that allows "in
field" re-charge of Ni-Cd battery packs from a convenient energy source such as an
automotive battery. The note includes transformer design and winding details.
Though designed for a specific case, circuit and principle employed should lend
itself to many or applications. (app note added 2/06)
AN26 Fast Charging Batteries with Zetex High Current PNP Transistors & Benchmarq
Controller ICs - Zetec Semiconductors Applications Notes High current, fast
switching PNP transistors are capable of replacing large packaged P-Channel
MOSFETs, when attention is paid to base drive requirements. This enables space
and performance efficient designs at much reduced cost. (app note added 6/06)
