Controller for the three-phase cascade multilevel converter used as shunt active filter in unbalanced operation with guaranteed capacitors voltages balance
Escobar Valderrama, Gerardo; Martínez Montejano, Misael Francisco; Valdez Fernández, Andrés Alejandro; Torres Olguín, Raymundo Enrique (2013-02)"The present invention comprises a controller for the cascade H-bridge three-phase multilevel converter used as a shunt active filter. Based on the proposed mathematical model, the controller is designed to compensate ... -
Fixed reference frame phase-locked loop (FRF-PLL) for unbalanced line voltage conditions
Escobar Valderrama, Gerardo; Torres Olguín, Raymundo Enrique; Martínez Montejano, Misael Francisco (2008-10)"The present invention relates to a system to implement a phase-locked loop (PLL) which is able to provide an estimation of the angular frequency, and both the positive and negative sequences of the fundamental component ... -
Repetitive controller for compensation of periodic signal
Leyva Ramos, Jesús; Escobar Valderrama, Gerardo (2016-12)"A repetitive controller scheme with positive feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located ... -
Repetitive controller to compensate for (61+-1) harmonics
Escobar Valderrama, Gerardo; Hernández Briones, Perla Gisel; Martínez Rodríguez, Pánfilo Raymundo (2015-04)"A repetitive controller scheme with two feedbacks one negative and one positive plus a negative feedforward introduces infinitely many poles on the imaginary axis located at j(6l+-1)omegao (l=0,1,2, . . . ,[infinity]) ... -
Repetitive controller to compensate for odd harmonics
Leyva Ramos, Jesús; Escobar Valderrama, Gerardo (2016-12)"A repetitive controller scheme with negative feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located ...
