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.

Voltage balancing in low‐voltage radial feeders using Scott transformers
IET Generation, Transmission & Distribution, 2014 Increasing use of heat pumps, micro‐generation, electric vehicles and energy‐saving technologies is expected to cause severe voltage imbalance on low‐voltage (LV) radial feeders and deteriorate the power quality seen by single‐phase (1Φ) and three‐phase (3Φ) LV connected consumers. To solve this problem, a Scott transformer‐based balancing technique is
