A power inverter is a device that converts energy in form of DC to AC energy. DC energy stored in batteries is converted to AC for household and industrial use. There are different types of inverters: square, modified square wave, trapezoidal, stepped sine wave, and sine wave inverters [1]. The sine wave inverter is more beneficial as it is highly efficient, compatible with a wide range of electronic devices, has quiet operation, less electromagnetic inference (EMI), and improved performance. Sinus 3.1 is an offline pure sine wave inverter designed by Samsonic Technologies and Consults 2023. The sinus 3.1 is a sine wave inverter board designed to meet the above requirements. A dedicated microcontroller (MCU) is used to design the inverter. This MCU handles all operations, including inverting, charging, protection, and other secondary functions.
