Hybrid transmission systems associated with line commutated converters (LLC) and voltage source converters (VSC) have gradually become a particular solution for high voltage direct current (HVDC) transmission. The full-bridge submodule (FBSM) based modular multilevel converter (FB-MMC) has gained significant attention for its dc voltage reversal and fault ride through capabilities. However, large...
In this paper, a novel hybrid modulation method is presented based on the analysis of the existing modulation method, the phase-shifted PWM modulation and the level-shifted PWM modulation. The novel modulation is best fitted for the active power filter based on the cascaded H-bridge converter. Itpsilas supported by the simulation with Matlab/Simulink. The simulation results show that the efficiency...
A novel power factor control and power flow control method for IGBT current source rectifier is proposed in this paper. Unlike the conventional control method in the a-b-c three-phase stationary frame, the proposed control is based on the d-q rotating frame. The proposed power factor compensation scheme can provide maximum achievable power factor under all operating conditions, including the regenerative...
