Abstract:

Two experimental high-power pulse modulators, incorporating a combination of semiconductor and magnetic switching, are described. The circuits, with average output powers of 2000 and 160 watts, were designed according to a new technique and are remarkably lightweight the 160-watt unit weighs approximately 5 lbs., the 2000-watt unit only 15 lbs. and efficient. By virtue of their solid-state construction, the modulators show promise of being extremely reliable and potentially long-lived. The basic circuit common to both units is adaptable to a wide range of output powers, types of load, and power-supply requirements. The 2000-watt modulator is designed for continuous operation from a conventional unregulated power supply peak power output is 1 megawatt in a 2-microsecond pulse. In contra t, the 160-watt modulator is intended for an application where power is supplied by a battery pack output pulse width is 1 microsecond, with .16 megawatts peak power. The circuit design principles incorporated into the two modulators are discussed, and detailed performance data for both circuits are presented. Autho
