ABSTRACT
To run an ion source several power supplies and other electronic equipment are necessary. The environment of the ion source electronics is dominated by high voltages of up to several hundred kilovolts. The chapter presents some modern electronic designs, which are neither conservative nor passive, but have specific and novel circuit configurations that protect them from high-voltage and plasma interference. With a test converter and some electronics the power supply can be operated as voltage- or current-controlled. The test electronics get their signals from two voltage dividers at the input and the output of the pulse switch. An insulated-gate bipolar transistor (IGBT) is a power-switching device that combines both high-speed capabilities and high-impedance characteristics of MOSFETs, and low saturation voltage characteristics of bipolar transistors. By the reverse connection of this turn the negative voltage pulse becomes positive and switches the transistor, which discharges the gate of the IGBT.
