| Abstract |
A solid state, high repetition rate power pulse generator has been developped to satisfy ENEL (ltalian Electricity Company) specifications. The main features of the generator are short pulse duration, low switching losses and good pulse shape with limited tail. The pulses are generated by means of four parallel solid state switching stages, working at an intermediate voltage of 4kV, and then raised to the required peak output voltage (60kV) by four step-up power pulse transformers. A novel, lossles circuit has been developped to recover the residual energy at the end of each pulse cycle and special attention has been payed to the reverse flow of energy in case of breakdown in the load. Particular care has also been devoted to the trigger pulse generator for the solid state switches. Preliminary tests on the prototype, with a simulated load, confirm the correctness of the design assumptions while development work continues on thermal and control aspects. |
