A 10 000 A programmable discharge system has been constructed for testing electrochemical propulsion elements and systems. The system is programmable for constant power and constant current and will respond to low frequency analogue waveforms from an external source.
To minimize the switching loss of high frequency thyristors, three kinds of multifinger gates and emitter designs are studied. The device characteristics were evaluated. The power loss during high frequency operation was measured. The rate of rise of forward current was studied.
