J. Arrillaga et al., NATURALLY COMMUTATED THYRISTOR-CONTROLLED HIGH-PULSE VAR COMPENSATOR, IEE proceedings. Generation, transmission and distribution, 142(2), 1995, pp. 219-224
An alternative to the thyristor controlled reactor is proposed based o
n the ability of the AC/DC convertor to absorb controllable reactive p
ower. The standard three-phase bridge configuration is modified, using
the concept of DC ripple reinjection, to achieve high pulse operation
without the need for passive harmonic filtering. A 36-pulse scaled-do
wn test system is used to verify the theoretical predictions.
