Beschreibung
Zusammenfassung:	The invention relates to the technology of UPS voltage source inverters, in particular to a UPS three-phase PWM voltage source inverter based on auto-disturbance rejection control. The inverter comprises an auto-disturbance rejection controller ADRC and a UPS three-phase PWM voltage source inverter. The UPS three-phase PWM voltage source inverter is a controlled object of the auto-disturbance rejection controller ADRC. The auto-disturbance rejection controller ADRC comprises a tracking differential controller TD, an expansion state observer ESO, and a non-linear state error feedback controllerNLSEF. The input end of the tracking differential controller TD is connected with an input signal and the output end is connected with the input end of the non-linear state error feedback controllerNLSEF and the output end of the expansion state observer ES. The input end of the expansion state observer ES is connected with the input end of the UPS three-phase PWM voltage source inverter. The output end of the non-linear
