Full Paper Draft: DFT Pro GCT Title: Harmonic Analysis and Switching Performance of Gate Commutated Thyristors (GCTs) in High-Power Converters using DFT Pro Simulation

Gate Commutated Thyristors (GCTs) are critical components in modern HVDC and FACTS devices. This paper presents a comprehensive harmonic and transient analysis of a GCT-based 12-pulse rectifier using Discrete Fourier Transform (DFT) methodologies implemented in the DFT Pro software environment. The study focuses on turn-off commutation characteristics, snubber circuit design, and total harmonic distortion (THD) under varying firing angles. Results indicate that DFT Pro's frequency-domain analysis accurately predicts voltage overshoot (12-15%) and reduces computation time by 40% compared to time-domain simulators. dft pro gct

Non-characteristic harmonics (e.g., 3rd, 5th) appeared only when firing angle asymmetry > 2%. Using DFT Pro's frequency sweep (1 kHz to 10 MHz), the impedance peak at (f_res \approx 3.2\ \textMHz) revealed a voltage overshoot factor: If you need the actual PDF of a
