Abstract: A high voltage solid-state rectifier includes multiple series connected ac-compensated diodes and series buffer resistors in a stepped spiral stack. The stack is encased in a sectionalized faraday shield which provides 360 DEG isolation from external rf electrostatic fields and provides external capacitance grading along the stack. Spark gaps between shield sections prevent excessive voltage build-up due to electrical discharges and are arranged in line of sight of each other to permit the ultra-violet light produced from one spark gap firing to stimulate the firing of the other spark gaps. A trigger spark-gap derives its voltage from an inductance in series with the solid-state rectifier. Any electrical discharges which result in an excessive voltage appear initially across the inductance, firing the trigger spark gap which in turn initiates the other spark gaps to fire by ultra-violet stimulation.
