DC stepped up voltage transformerless battery charger
Patent
·
OSTI ID:5277793
A battery charger that takes energy from a battery and steps-up the voltage to charge another battery. The direct current, going into the charger's circuit goes through the voltage regulator and then to a switching voltage regulator (the integrated circuit) and a few external components which generates the energy to charge the output capacitor. The output capacitor voltage is controlled by a resistive voltage divider network, and energy stored in the output capacitor is transferred through a diode and a current limiter to charge the battery.
