Development of High Voltage Pulse Power Supply for Microwave Tube Applications

This paper describes about the design and development of high voltage DC pulse power supply for high power applications. The system has variety of features such as independent control of Pulse Repetition Frequency (PRF), Pulse Duration $({T_{on}})$ and pulse amplitude. PC based wireless pulse generation and control unit with Graphical User Interface (GUI) having variable/controlled PRF (10Hz-1 kHz) and Ton $(10-100{\mu} \mathrm{s})$ is developed for gating pulse generation. Two sets of −25kV, 10A pulse power supplies are connected in series to achieve −50kV, 10A pulse output voltage. High voltage DC pulse power supply is used for the characterization of high power microwave tube and testing applications. To verify the proposed design, simulation and experimental results on resistive load are presented in this paper.
