With the continuous development of renewable energy, solar power generation systems have been widely used around the world. In these systems, the inverter plays a vital role. It is not only responsible for converting the direct current (DC) generated by solar panels into alternating current (AC) for use in homes or power grids, but also plays a key role in system efficiency, stability and safety. This article will take a deep look at the basic principles of inverters, technological advances and their importance in future energy systems. 1、The basic principle of inverter The basic principle of the inverter is to convert the direct current generated by the solar panel into alternating current for use in the home or power grid. The direct current is switched into an alternating current waveform through the power electronic components (such as IGBT or MOSFET) inside the inverter, and the high-frequency harmonics are eliminated through the filter. The voltage and frequency are adjusted through the [...]
