Solar Battery Chargers for NiMH Batteries
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006This paper proposes new solar battery chargers for NiMH batteries. First, it is shown that existing charge-control methods can fail when charging by solar arrays in changing environmental conditions. This article discusses the reasons for the failure and introduces new voltage and temperature-based charge- control techniques.

2007 International Conference on Electrical Machines and Systems (ICEMS), 2007
This paper presents the simulation and hardware result of high voltage charger. It also presents the modeling of lead-acid battery to get the dynamic charging and discharging behavior of the battery for simulation purpose. Triggering pulses for rectifier are generated using inverse cosine firing scheme.

Switching-mode Battery Charger
2003It was mentioned in section 4.5 that the switching-mode charger will be treated in a standing alone chapter. The reason of doing so was also given. Without wasteful verbiage, we shall treat first a boost charger, then a charger in buck mode. For both chargers, some circuit blocks are given detailed analytical expressions and their derivations ...
