A Unipolar/Bipolar High-Voltage Pulse Generator Based on Positive and Negative Buck-Boost DC-DC Converters Operating in Discontinuous Conduction Mode
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper presents a new high-voltage pulse generator, which is based on positive and negative buck-boost (BB) converters fed from a relatively low voltage dc supply. The proposed generator is able to generate unipolar ...
A hybrid boost modular multilevel converter-based bipolar high voltage pulse generator
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
Conventional Modular Multilevel Converter (MMC) with Half-Bridge Sub-Modules (HB-SMs) can be used effectively as a solid-state high-voltage pulse generator to chop a high-voltage dc input into a bipolar pulsed output voltage ...
Four-Arm Three-Phase Modular Multilevel Converter (4A-TPMMC)
(
Taylor and Francis Inc.
, 2017 , Article)
In this paper a Four-Arm Three-Phase MMC (4A-TPMMC)-based DC-AC converter is proposed. The proposed converter generates a three-phase output voltage using a lower number of components, which reduces the converter complexity ...

Korean Institute of Power Electronics
, 2017 , Article)
This paper presents a buck-boost converter-based bipolar pulse generator, which is able to generate bipolar exponential pulses across a resistive load. The concept of the proposed approach depends on operating the involved ...
Arrester-less DC fault current limiter based on pre-charged external capacitors for half-bridge modular multilevel converters
(
Institution of Engineering and Technology
, 2017 , Article)
The half-bridge modular multilevel converter (HB-MMC) is one of the most promising topologies for high-voltage direct current (HVDC) systems. Unlike full-bridge MMC (FB-MMC) and clamp double sub-module MMC (CDSM-MMC), ...
A boost-inverter-based bipolar high-voltage pulse generator
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
Bipolar repetitive high-voltage pulse generators are commonly used in modern pulsed power applications. Conventionally, bipolar high-voltage pulses can be generated by adding a high-voltage H-bridge at the output stage of ...
A Nine-Phase Six-Terminal Concentrated Single-Layer Winding Layout for High-Power Medium-Voltage Induction Machines
(
Institute of Electrical and Electronics Engineers Inc.

This paper proposes a new winding layout for high-power medium-voltage nine-phase induction machines (IMs) based on a single-layer concentrated winding layout having a unity winding factor. The machine is fundamentally an ...
Postfault operation of a nine-phase six-terminal induction machine under single open-line fault
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper studies the postfault control of a nine-phase six-terminal induction machine (IM) during single open-line fault, which was recently proposed for high-power medium-voltage applications as a promising alternative ...
A sensorless Kalman filter-based active damping technique for grid-tied VSI with LCL filter
(
Elsevier Ltd
, 2017 , Article)
Employing the LCL passive filter in inverter-based distributed generation to ensure high quality power delivery comes at the expense of poor performance due to the resonance phenomenon. Literature elucidated several active ...
