Compact all solid state pulsed power generator driven by FPGA

Abstract

High-reliability, high repetition rate and compactness of pulsed power generators have been required for spreading industrial applications. The control of pulsed power generator becomes more complicated with the increase of functions. An all solid state pulsed power generator can be easily controlled by using a field programmable gate array (FPGA). The pulsed power generator is consisted of a controller, a charger, insulated gate bipolar transistor (IGBT) switches, magnetic switches and etc. The performance of the pulsed power generator such as variable pulse repetition rate and diagnosis of incorrect operation is achieved by rewriting the programming of Verilog hardware description language (HDL). The pulsed power generator using a FPGA becomes more compact in comparison with conventional pulsed power generators using logic ICs.
