Abstract

This paper describes about the efficient design of pulse power supply for mercury-free plasma UV-lamp based applications. The single phase AC-DC Unity Power Factor (UPF) converter along with flyback converter is employed to design efficient and high voltage pulse power supply. The system has fixed Pulse Repetition Frequency (PRF), Pulse Duration (T on ) and pulse amplitude. Design and analysis of pulse power supply with output voltage of -5kV and output current of 2.5A with PRF (25 kHz) and T on (2 μs), fed from single phase AC voltage is presented. To verify the proposed design, the topology is simulated in MATLAB and simulation results on resistive load are presented in the paper.
