HVDC - Current Source Converter - Minimum DC Power flow

  1. Jul 26, 2016 #1

    I was reading about the differences between Current Source Converters and Voltage source converters.
    One main difference was that Current source converters need to have a minimum DC power flow of 5-10% while VSC do not have a min flow requirement. It was also called a deadband.
    Why is this? Does it have to do with the thyristors? If so, how?

    We have no real idea what you're talking about.

    How about pasting in the paragraph that confused you ?

    Hi Jim,

    This is the article I was reading on the technological differences between different types of DC/AC convertors( LCC vs. VSC ).
    There is a table on page 3 that compares the 2 technologies side by side.
    At Minimium DC Power, it is said that the LCC requires a flow of at least 5-10% of the rated power.
    I am trying to understand why this is the case.
