A multilevel voltage-source converter system with balanced DC voltages [PDF]

Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002
In this paper, a multilevel voltage-source converter system is proposed for high-voltage, high-power applications such as back-to-back interconnection of power systems, large induction motor drives, and electrical traction drives. Multilevel voltage-source converters have a voltage unbalance problem in the DC capacitors.

Experimental Validation of Nonlinear Control for a Voltage Source Converter

IEEE Transactions on Control Systems Technology, 2009
In this brief, we consider reactive power and dc voltage tracking control of a three-phase voltage source converter (VSC). This control problem is important in many power system applications including power factor correction for a distribution static synchronous compensator (D-STATCOM).Traditional approaches to this problem are often based on a ...
