Power electronics is a field of electrical engineering that focuses on the conversion and control of electrical power using electronic devices. It involves the use of components like transistors, diodes, and capacitors to manage the flow of electricity efficiently. This technology is essential for various applications, including renewable energy systems, electric vehicles, and industrial automation. The primary goal of power electronics is to improve energy efficiency and reliability in electrical systems. By converting electrical energy from one form to another—such as from AC to DC—power electronics enables better performance and control in devices like inverters and power supplies.
