High pulse AC/DC convertors and their application to HVDC transmission. [PDF]

open access: yes, 1992
AC/DC convertors used in HVdc transmission systems inject harmonics into their associated AC and DC systems. A conventional approach to filter these harmonics is to use passive filters on both AC and DC sides of the convertor.

Influence of DC Voltage Droop Settings on AC System Stability [PDF]

open access: yes, 2012
This paper presents a methodology to study the impact of different DC voltage droop settings on the AC system stability. When several Voltage Source Converters (VSC) in a DC system jointly control the DC voltage by means of droop control, an outage of ...

Novel single‐armed modular multilevel converter for reducing total converter capacitance

open access: yesIET Power Electronics, 2021
During normal operation of a conventional Modular Multilevel Converter (MMC), half of its capacitors remain bypassed at any time instant, increasing the total required capacitance for converter operation, and in turn leading to a larger size and volume ...

Development of a current source resonant inverter for high current MHz induction heating

open access: yesIET Power Electronics, 2022
High frequency industrial induction heating processes typically employ resonant inverters to reach high efficiency at high power levels. Advancements in wide band gap (WBG) device technology has made it feasible to push the possible frequency of these ...

Tradeoffs between AC power quality and DC bus ripple for 3-phase 3-wire inverter-connected devices within microgrids [PDF]

open access: yes, 2011
Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa.

DC‐side current compensation control in the rectifier terminal for power variations in back‐to‐back converters

open access: yesIET Renewable Power Generation, 2021
Back‐to‐back (BTB) converters, which consist of an AC/DC rectifier cascaded with a DC/AC inverter, have been widely adopted in the interconnection of power systems.
