In modern times, mobile devices have become very popular, because of the ease of use even outside the room though. Its simplicity to carry anywhere, of course, making mobile devices requires a source of electricity from the battery. The use of a battery is indeed the best solution, but the battery has limitations in providing electricity. For this reason, we need another device that can charge the battery anywhere and anytime. For this reason, a power bank was created to charge mobile devices everywhere. Basically the power bank is an electronic device consisting of a lithium-ion battery and a DC to DC boost converter circuit, which is able to change the voltage of 3.7 volts from the battery to 5 volts DC. DC to DC boost converter system Works with the high frequency switching method so that it is quite efficient in consuming battery power. The DC to DC boost converter consists of main components such as ferrite core inductors, mosfets, ultrafast diodes and filter capacitors. Electri...
