This work presents a three-phase AC-AC converter, with independent phase control, based on matrix-converter structure. This converter is applied to electrical energy saving on the public lighting systems by means of ...
Self-powered bipolar gate-driver power supply circuit for neutral-point-clamped converters
(2018)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The design of gate-driver power supply (GDPS) circuits for multilevel neutral-point-clamped converters is a challenge due to the large number of power switches required and the fact that each device presents a different ...
LCLC resonant converter as maximum power point tracker in PV systems

Carrier-based PWM strategies for the comprehensive capacitor voltage balance of multilevel multileg diode-clamped converters
(IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
This paper presents four carrier-based PWM
strategies for diode-clamped converters of any number of levels and any number of legs (phases). These carrier-based PWM
strategies guarantee the dc-link capacitor voltage balance ...
