SC B4 “HVDC and Power Electronics”
Activity Report
Presented by: John McNichol (Manitoba Hydro)

SC B4 HVDC and Power Electronics
General Subject Matter
• LCC (Line Commutated Converters) - Conventional technology for
HVDC transmission utilizing thyristors as the switching technology
for rectifier and inverter operation
• VSC (Voltage Source Converters) – “Newer” Technology for HVDC
conversion using IGBT switching technology. It is currently applied to
schemes of less than 1400 MW. Technology is growing and its
applications can include passive loads, wind and off shore oil rigs.
Losses and IGBT rating are limiting factors that are gradually being
overcome.
• FACTS (Flexible AC Transmission Systems) – Systems involving the
controlled switching of capacitors and/or reactors to facilitate and
stabilize increased power transmission. The elements may be series or
shunt connected
