Abstract

The demand for efficient and high quality electricity supply continues to grow, especially in areas not yet reached by the main power grid. Inverter are a key solution to convert DC voltage sources, such as batteries or solar panels, into AC voltage usable for. Various electrical devices. This study aims to design and implement an inverter based on a class D amplifier using a full bridge configuration. The system uses a 48VDC input and convert it into 230VAC with the help of a DC to DC step up circuit and a conventional step up transformer. A class D amplifier was chosen due its high efficiency in processing PWM signal into pure sine waves through a low pass filter (LPF). Testing results show that the inverter is capable of generating pure sine wave output with efficiency varying depending on the load, reaching maximum of 88% at low load and decreasing under high load. The system is also equipped with over voltage protection and under voltage protection to ensure operational reliability. The designed inverter has proven to perform well with various types of loads and shows potential for application in household backup power systems and renewable energy setups.
