Single-sensor-based three-phase permanent-magnet synchronous motor drive system with luenberger observers for motor line current reconstruction
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
This paper presents an algorithm that enables single-sensor operation of vector-controlled three-phase permanent-magnet-synchronous-motor voltage source inverter (VSI)-based drive systems. The closed-loop operation is ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
