One application of a separately excited generator

is in the field of renewable energy, specifically in wind turbines. Separately excited generators are commonly used in wind turbine systems to convert mechanical energy from the rotating blades into electrical energy. The generator's excitation field is supplied with a separate DC power source to control the output voltage and power quality of the generated electricity. This allows for better control and regulation of the power output, making it suitable for feeding into the grid or storing in batteries for later use.
