A modular multilevel series/parallel converter for a wide frequency range operation
(IEEE Transactions on Power Electronics, 2020)
A new three-phase low THD power supply with high-frequency isolation and 60V/200A regulated DC output
(2001-10-22)
This work proposes a new isolated high power factor 12kW power supply based on an 18-pulse transformer arrangement. Three full-bridge converters are used for isolation and to balance the DC-link currents, without current ...

The Asymmetric Alternate Arm Converter: A Compact Voltage Source Converter Design for HVDC
(2018)
The Modular Multilevel Converter (MMC) has become one of the most practical topologies for integration of renewable energy power plants into the grid, through submarine HVDC cables and HVDC lines. Nonetheless, the MMC ...
Voltage-source active power filter based on multilevel converter and ultracapacitor DC link
(2006)
A new topology for active power filters (APF) using an 81-level converter is analyzed. Each phase of the converter is composed of four three-state converters, all of them connected to the same capacitor dc link voltage and ...
A DC-DC converter based on the three-state switching cell for high current and voltage step-down applications
(2013-01-01)
This paper presents a pulsewidth modulation dc-dc nonisolated buck converter using the three-state switching cell, constituted by two active switches, two diodes, and two coupled inductors. Only part of the load power is ...
