Grid-connected control of high-speed permanent magnetic generator based on Z-source inverter

In this paper, the use of the Z-source inverter with grid connected permanent magnetic generator systems is researched. The system used the maximum boost control can boost and generate the desired output voltage efficiently when the low voltage of the generator is introduced at low speed, also with lower voltage stress across the IGBT. Through this research, the grid-connected control method and the strategy of high-speed power generation system is acquired, the operation reliability of the generator unit is improved and the theoretical foundation for the application of Z-source inverter in high-speed power generation system is laid.
