A bi-directional boost converter-based non-isolated DC-DC transformer with modular solid-state switches for medium-/high-voltage DC grids
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In this paper, a bi-directional non-isolated dc-dc transformer is proposed, which can be used for connecting different dc voltage levels in medium-/high-voltage dc grids. The proposed dc-dc transformer is based on the ...
Enhancing the DC voltage utilization of twelve-switch voltage source inverter feeding symmetrical/asymmetrical nine-phase loads
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Twelve-Switch Nine-Phase Inverter (TSNPI) can be used to feed three independent three-phase loads or nine-phase load such as nine-phase machines. It provides dc-ac conversion with a reduced number of switches, as only ...
A four-switch based long-cable-fed five-phase induction motor drive system
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In applications where motors are fed from low voltage variable-frequency drive (VFD) through long cables, a step up transformer is commonly used to boost the converter output voltage in order to compensate for the cable ...
Operation of three-phase modular multilevel converter (MMC) with reduced number of arms
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Conventional three-phase MMC consists of six-arms, each arm is controlled to generate unipolar voltage ranging from zero to Vdc where Vdc is the input DC voltage. Each arm voltage has two components (DC and AC components). ...
Half-bridge modular multilevel-based HVDC converters with external pre-charged capacitors for dc fault current suppression capability
(
Institution of Engineering and Technology
, 2016 , Conference Paper)
Half-Bridge Modular Multilevel Converters (HB-MMCs) are defenseless against DC side faults. Different types of DC Circuit Breakers (DCCBs) assisted with arrester banks/damping resistors such as solid-state CBs and hybrid ...
High-voltage pulse generator based on capacitor-diode voltage multiplier centrally fed from dc-dc boost converter
(
Institution of Engineering and Technology
, 2016 , Conference Paper)
High voltage pulse generators are commonly used in water treatment applications. In this paper, a high voltage pulse generator with closed loop control on its output voltage is presented. The high-voltage pulse generator ...
Multi-module high voltage pulse generator based on DC-DC boost converter and CDVMs for drinking water purification
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
High pulsed electric field (PEF) can be used effectively in drinking water purification, by applying it across the water sample to be treated. Application of sufficient high PEF guarantees killing of harmful germs and ...
