Abstract

Because of the fast growth of the Internet of Things (IoT), it is now necessary to have a reliable power source for the use of IoT devices. Any IoT gadget will require power to function. A gadget will always require a certain amount of voltage and current, whether it comes from a power outlet or a battery. Power is the result of these two variables (voltage and current). The device's energy is defined as the quantity of power utilised during a given time. Some of these devices consume small power and this led to discontinuous conduction mode (DCM) operation of a dc- dc converter. Therefore, a dc- dc zeta converter working in DCM is suggested, and the converter is stabilised using a hybrid control method based on the control Lyapunov function. A Lyapunov function is a scalar function defined on the phase space that may be used to verify an equilibrium point's stability. Circuit design and development, as well as microcontroller programming will be conducted for this project. The project expected that a stable output voltage will be produced although the changes at the input voltage and load.
