Abstract :
Traditional magnetron pulsers have mainly been based on energy storage PFNs and discharge switches. With advances in semiconductor switch technology the direct drive pulser is emerging to challenge the PFN approach. This paper describes a high voltage, high power switchmode supply designed for charging a large storage capacitor in a direct magnetron pulser, which is employed in a medical therapy application. The demands of the load system and the design of the power supply required to produce full rated power at both 65 kV and 43 kV are described.
