Double input converters for different voltage sources with isolated charger

Abstract

This paper presents the double input converters for different voltage input sources with isolated charger
coils. This research aims to increase the performance of the battery charger circuit. In the circuit, there are
the different voltage levels of input source. The operating modes of the switch in the circuit use the
microcontroller to control the battery charge and to control discharge mode automatically when the input
voltage sources are lost from the system. The experimental result of this research shows better performance
for charging at any time period of the switch, while the voltage input sources work together. Therefore, this
research can use and develop to battery charger for present or future.
