Designing at Very High Voltages: Everything Changes

The Need For High VoltageStart with Physical DimensionsMove on to Passive ComponentsConnectors and CablesHigh-Voltage Active Devices Are Also NeededGiven the challenges and risks, why do design engineers even consider using these voltages at all? Iteither because the engineer has no choice, or because ita really good and necessary idea. The applications fall into two broad groups: In the realm of "the engineer has no choice," scientific, medical, and physics instrumentation need high voltages in specialized equipment such as X-ray machines, to develop high-intensity fields, ionize atoms, and accelerate electrons and other particles. The same applies to vacuum tubes that still need high-power broadcasting or even moderate-power microwave and mm-wave transmitters. In a more common application, even a commercial neon sign needs several kV to ionize the noble gases inside. Note that many of these applications require kilovolts and more, but at relatively modest currents of around 100mA.
