Self-precharge in single-leg flying capacitor converters [PDF]

open access: yes, 2009
Flying Capacitor (FC) multilevel pulse width modulated (PWM) converters are an attractive choice due to the natural voltage balance property. During start-up of the converter, care has to be taken that the power switches are not exposed to voltage ...

Voltage balancing in low‐voltage radial feeders using Scott transformers

open access: yesIET 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

Capacitor Voltage Balancing Strategy of NPC Three-level Dual-active Bridge Converter Based on Redundant Vector

open access: yesKongzhi Yu Xinxi Jishu, 2023
The neutral point clamped (NPC) three-level dual-active bridge (DAB) converter can be applied at higher voltage levels and in a wider operating range than the traditional DAB converter, and therefore it is more promising in future applications.

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

open access: yesProceedings 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.
