High Power Modulator Techniques (SCR).
Abstract
Development and test of a 65KV Silicon Controlled Rectifier demonstrates the application of solid state devices and their inherent reliability in high power pulse modulator techniques. The design exploits the high voltage and high current capabilities of the SCR. Eighty devices in series yield a minimum holdoff voltage of 65KV; the test modulator switches pulse currents of 375 amperes although the SCRs have a 1000 ampere minimum peak pulse current capability. The 65KV SCR switch assembly employs a 'building block' concept utilizing ten, 6.5KV SCR switch assemblies. An electro-optical triggering technique eliminates trigger pulse transformers which require high voltage insulation between primary and secondary windings. These techniques are applicable to even higher voltage SCR switch assemblies. (Author)
