This final project aims to create a design of push-pull converter that is used in charging system of accumulator battery whose power source comes from solar panel. The solar panel has a maximum power of 150 watts with a terminal voltage in a no-load state of 21.67 volts. Battery accumulator used is of sealed lead acid (SLA) capacity of 7.5 Ah with a nominal voltage of 12 volts. The solar panel …
