(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In an effort to minimize the power disruption between a dc grid and ac grids that host power converters during ac and dc network faults, this paper proposes a novel converter station structure to improve ac and dc fault ...
A Neutral-Point Diode-Clamped Converter with Inherent Voltage-Boosting for a Four-Phase SRM Drive
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
This article proposes a new asymmetric neutral-point diode-clamped (NPC) multilevel converter for a four-phase switched reluctance motor drive. The inbuilt NPC clamping capacitors are used for both voltage level clamping ...
New voltage regulation techniques for low voltage radial feed PWM inverter based distributed networks
(2010 , Conference Paper)
Grid voltage rise problems occur, especially at light loads, due to the proliferation of distributed generation. Two techniques are proposed for regulating the voltage in low voltage radial networks when inverter based ...
