Description/Abstract Design, construction and testing of a prototype HV power supply for the klystrons of the 300 MeV racetrack microtron (MUSL) of the University of Illinois are described.^Regulation of 0.02% is achieved with three voltage feedback loops.^Two loops to thyristor phase control circuits on the ac primary of a 12-phase rectifier transformer regulate its output to within + or - 0.2% (line regulator).^A third loop controls a series-connected tetrode to bring the output to within + or - 0.02% of the preset value.^The voltage drop across the tetrode can be set between 800 V and 1600 V; this setting is maintained by one of the loops to the line regulator.^Other unique features are protective circuits that limit the fault current to 150% of the rated current when the klystron and/or the tetrode spark over.^Voltage spikes generated by the thyristors are attenuated with LP-filters.
