A Simple Virtual-Vector-Based PWM Formulation for Multilevel Three-Phase Neutral-Point-Clamped DC–AC Converters including the Overmodulation Region
(2022-02-01)
Article
Accés obertNeutral-point-clamped (NPC) power conversion topologies are among the most popular multilevel topologies in current industrial products and in industrial and academic research. The proper operation of multilevel three-phase ... -
Comparison of modulations and dc-link balance control strategies for a multibattery charger system based on a three-level dual-active-bridge power converter,
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés obertThis paper focuses on the study of a charger for two batteries connected in series. From the three-phase grid, the batteries are charged through a three-level neutral-point-clamped (NPC) ac-dc converter in cascade with a ... -
Overmodulation of n-level three-leg DC-AC diode-clamped converters with comprehensive capacitor voltage balance
(IEEE Press. Institute of Electrical and Electronics Engineers, 2013-05)
Article
Accés restringit per política de l'editorialThis paper presents a novel pulsewidth modulation (PWM) strategy for n-level three-leg semiconductor-clamped dc–ac converters in the overmodulation region, with dc-link capacitor voltage balance in every switching cycle. ...
