ABSTRACT
This chapter introduces some units used to measure large values of power. The wind turbine is one of the most promising energy sources, and it has attracted much attraction in recent decades and penetrated utility systems deeply compared to other renewable sources. The wind turbine is modern equipment to convert the wind’s dynamic energy into electrical energy. Two types of wind turbines are used: vertical axis and horizontal axis turbines. The output voltage and frequency of wind turbines are unstable as the wind speed is variable. The wind speed is unstable and changes from time to time in a certain speed range. Wind turbine and solar panel energy are clean and renewable. The super-lift Luo converter is very good at high-voltage transformation and thus was used in the solar panel energy system. The DC/DC converter is the positive output super-lift Luo converter with double closed-loop control.
