Dual Power Source Switching Control to Li-Ion Battery Charger for Medical Power System Applications

This work describes the design and simulation of a dual power source switching control to Li-Ion battery charger for medical power system applications. The proposed circuit consist of two sections. First section is a dual power source switching control used to switching between the main power and the backup battery power and a Li-Ion battery charger used to control the charging and discharging li-Ion battery. The goal of the study is to propose a new architecture for the power multiplexer without incurring significant efficiency degradation or cost is a tricky challenge and a control method of charging and discharging lithium-ion battery to prolong its lifetime.
