Abstract

Multi-pulse rectification technology is widely used in high-power rectification field to reduce harmonics and increase power factor.A new 36-pulse rectification system based on stretch triangle connection of transformer is proposed and simulated by MATLAB/Simulink in this paper.Its working principle and output characteristics are analyzed.The output voltage waveforms and current harmonic contents of two multi-pulse rectification systems are compared and analyzed.The impacts of unbalanced input voltage on different multi-pulse rectification systems are also studied.The simulation results are in accordance with the theoretical analysis.Conclusion is drawn that the 36-pulse rectification system can reduce harmonic pollution and smooth output DC voltage effectively

and gains stronger capability to resist the unbalanced input voltage than the conventional 6-pulse rectification system.
