Abstract
A high power resonant three phase switch mode power supply with low output ripple has been constructed at University of Wisconsin to drive a klystron tube. Output voltage stabilization has been achieved by adjusting switching frequency toward resonance to compensate for capacitor bank droop. The power supply input is connected to a 900V electrolytic capacitor bank and three transformers with loosely coupled resonant secondaries are connected to a doubling three phase rectifier to provide an 80kV, 40A output. A snubber and crowbar sparkgap protects the klystron in the event of an internal arc, while output filters reduce voltage ripple in the output.
