harmonic cancellation pwm
harmonic cancellation pwm
(OP)
Hi,
my company plans to use an ABB HVDC light converter system. In the technical description the keyword "harmonic cancellation PWM" is lined out. What I understood so far is that this feature was developed to reduce harmonic distortion of converters since avoiding harmonics is the best filter technology you could imagine.... Does anybody know more about how this works?
Best regards, Patrick

RE: harmonic cancellation pwm
first thanks for the rapid answer.
Unfortunately there is not much more precise information than that I cutted out of the ABB brochure. What I also read is that the showed general AC filter is always used and tuned to the specific HVDC variant. However I am more curious how the switching is performed / controlled.
