Generalized PWM-based method for multiphase neutral-point-clamped converters with capacitor voltage balance capability López, Iraide; Ceballos Recio, Salvador; Pou, Josep; Zaragoza Bertomeu, Jordi; Andreu, Jon; Ibarra Basabe, Edorta; Konstantinou, Georgios (2017-06-12)
Open AccessThis paper presents a generalized pulse width modulation (PWM)-based control algorithm for multiphase neutral-point-clamped (NPC) converters. The proposed algorithm provides a zero sequence to be added to the reference ...
Single-carrier phase-disposition PWM techniques for multiple interleaved voltage-source converter legs Konstantinou, Georgios; Capellá Frau, Gabriel José; Pou, Josep; Ceballos Recio, Salvador (Institute of Electrical and Electronics Engineers (IEEE), 2017-10-26)
Open AccessInterleaved converter legs are typically modulated with individual carriers per leg and phase-shifted PWM (PS-PWM) as it facilitates current balancing amongst the legs. Phase-disposition PWM (PD-PWM), despite the better ...
Study and comparison of discontinuous modulation for modular multilevel converters in motor drive applications Picas, Ricard; Zaragoza Bertomeu, Jordi; Pou, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Capellá Frau, Gabriel José (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
Open AccessDiscontinuous modulation applied to modular multilevel converters is an effective method for reducing the capacitor voltage ripples. In this paper, the discontinuous modulation is adapted and used in a motor drive application. ...
