This work concerns the reduction of the state-space system of a single-phase active-front-end (SP-AFE), in order to evaluate system stability using fewer variables. Through nondimensionalization, the 'small' parameters of the system are identified, the leading-order terms are computed and the number of Ordinary Differential Equations (ODEs) in the model is thereby reduced by 25%. As both the full and the reduced model of the SP-AFE are Non-Linear Time Periodic (NLTP), stability is evaluated by taking into account the corresponding linearized system about its time-periodic steady-state operating point; excellent agreement is found between stability calculations on the full and reduced systems. © 2019 IEEE.

Abstract
This work concerns the reduction of the state-space system of a single-phase active-front-end (SP-AFE), in order to evaluate system stability using fewer variables. Through nondimensionalization, the 'small' parameters of the system are identified, the leading-order terms are computed and the number of Ordinary Differential Equations (ODEs) in the model is thereby reduced by 25%. As both the full and the reduced model of the SP-AFE are Non-Linear Time Periodic (NLTP), stability is evaluated by taking into account the corresponding linearized system about its time-periodic steady-state operating point; excellent agreement is found between stability calculations on the full and reduced systems. © 2019 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
