Abstract

This paper presents a controlled transition bridge (CTB) converter that uses a non-trapezoidal amplitude modulation in attempt to reduce filtering requirement in high-voltage direct current (HVDC) transmission systems. To achieved variable output ac voltage (modulation index control) over wide range, as expected during a black-start, cell capacitor voltage balancing of the CTB converter is decoupled from the modulation index and power factor by injecting a 3^rd harmonic component into the modulating signal of each phase. This 3^rd harmonic extends the region around voltage zeros, where the cell capacitor voltages can be balanced, by ensuring that each limb is alternatively clamped to the positive and negative dc rails, every fundamental period to allow recharge of the cell capacitors from the dc link. The effective of the presented non-trapezoidal modulation method for operation of the CTB converter over full modulation and power factor range is confirmed by simulation, including its scalability to high applications.
