DC DC converters are electronic devices that convert direct current (DC) from one voltage level to another. These converters are essential components in many electronic devices, including computers, mobile phones, and power supplies. They are also widely used in renewable energy systems, such as solar panels and wind turbines. DC DC converters can either increase or decrease the voltage level, depending on the application. As technology advances, DC DC converters are becoming more efficient and compact, making them increasingly popular in various industries.
