A Power Converter serves as a device that converts current from one voltage level to another. This is crucial in applications where the available voltage needs to be changed to accommodate a specific requirement. These converters are widely used in electronics and power systems, where they help to step down the voltage from the battery level to the level required by the device components. They are also essential in renewable energy systems, where they convert the variable output from solar panels or wind turbines into a steady voltage suitable for batteries or grid connection.
