D-STATCOM based on a transformer-isolated chain-circuit inverter
Yongqiang Zhu · Journal of Tsinghua University(Science and Technology) · 2005
A new main electrical circuit topology was developed based on a transformer-isolated chain-circuit inverter. The system characteristics were analyzed using a Matlab simulation of the phase-shift Space Vector Modulation pulse control strategy. The control method compensates for unbalanced loads as a function of the DC voltages shared by the three phases. Tests on a ±10 kVar system show that the topology and the control system are effective.
