  • DC/DC Conversion
    The MCP1630 High Speed PWM is interfaced to the PIC16LF818 to develop a complete NiMH battery charger with fuel gauge capability.
  • Fully Integrated Fast Battery Charger with PWM current control and Microprocessor on Board
    Because ofthe tough algorithm implemented, since portability is anyway needed in many elec¬ tronic equipment, the demand for a single chip battery charger with microprocessor on board becomes thougher and thougher. Basically the circuit architecture, centered around an high efficiency PWM current controller (Imax = 1.5 A), contains an 8 bit A/D converter and finally, an … … and allows the implementation ofmany ofthe algorithms used for all ofthe most popular batteries (NiCd, NiMH ).
  • Battery Charger
    Linear Technology's 500 kHz LT1510 current mode pulse-width-modulation ( PWM ) battery charger delivers up to 1.5 A charging current. … as well as the current charging needed by nickel cadmium (NiCd) and nickel metal hydride ( NiMH ) batteries.
  • New Components and Design Methods Bring Intelligence to Battery Charger Applications
    4-Cell NiMH (Typical) Charger Efficiency. For applications that require intelligent power manage- ment solutions like battery chargers, the combination of a microcontroller and MCP1630 high-speed PWM is very powerful.
  • Smart Power/power integrated circuits, technology and applications: Proceedings
    ABSTRACT This paper presents a fast battery charger capable of charging NiCd and NiMH batteries using a low cost microprocessor for battery monitoring. The current implementation uses a standard microprocessor, PWM controller and discrete power MOS device.

  • Development of a universal adaptive battery charger as an educational project
    The input and output performance of the developed universal charger will be shown by two measurements. The measurement has been taken by charging a battery pack of 10 NiMH cells which results in a battery voltage of about UB = 14.5 V. The switching frequency of the PWM is fs = 50KHz as can be seen by the inverter output …
  • CR4 - Thread: Battery Pack for Warm Hands... Ski Glove
    The charger is light and sophisticated, and the batteries do not self-discharge quickly: last time I charged the pack was 2 months ago, and the tool still indicates that the batteries are fully charged. I wonder if you could make a PWM controller that would provide just 4 watts -- maybe with … Second best would be AA NiMH "hybrid" batteries.
