Research for Frequency Conversion Control in Air Supply System of Hydrogen Power

In order to make the flux of air flow satisfy the request of the generating electricity of the Hydrogen Power based on the PEMFC along with the change of the loads , the economy energy principle of frequency conversion adjustable-speed control of the induction electromotor is analyzed and the necessity that the air supply system adopted the AC frequency conversion adjustable-speed control is discussed. At the same time, the AC motor in the air supply system of the hydrogen power based on the PEMFC to adopt the vector control technology is presented. By means of comparing several scheme of the vector control, the schematic of the indirect rotor-flux-oriented control of a current controlled voltage-source inverter-fed induction machine drive is introduced , and the simulation study is conducted.
