In previous days, the lifetime of the battery in satellite is less. The challenge is to increase lifetime of the satellite by using the electronic circuit. This paper proposes a new design that can be used as a tool for increasing the lifetime of the batteries used in the satellite. Normally the satellite gets the energy from sun aswell as battery for its day to day activities. During the night time the satellite could not get the energy from the sun and so it gets the energy from battery only. During the time (6-10 AM & 2-6 PM), the satellite gets the energy from both sun and battery. And during the time (10 AM to 2 PM) the satellite fully gets the energy from sun but at the same time the battery will be charged from solar power. In this project the life time of the power consumption is decreased by means of a booster circuit. The project presents the control strategy and power management for an integrated 3 port converter which interface one solar input port, one bidirectional battery and an isolated output port.
