How can we convert a DC current to an AC current?

Image
Converting Direct Current (DC) to Alternating Current (AC) is a fundamental process in modern electrical engineering, enabling the operation of a myriad of devices that require AC power. Whether it's for household appliances, industrial machinery, or renewable energy systems, the ability to convert between these two types of currents is essential. Let's explore the techniques used to achieve this conversion. Inverters : The most common method for converting DC to AC is through the use of inverters. Inverters come in various types, including square wave, modified sine wave, and pure sine wave. Pure sine wave inverters produce a smooth, high-quality AC output similar to what you'd get from a standard power outlet, making them suitable for sensitive electronics. Inverters work by rapidly switching the DC input on and off to create an AC waveform. Transformer-based inverters : These inverters use transformers to step up the voltage of the DC input before converting it to AC
