The Advanced Reverse Switching Rectifier RSR Modulator is a unique line-type pulse modulator concept in which Pulse Forming Networks PFNs are AC resonantly charged directly from an AC source and discharged by solid state RSR switches. Its conception was motivated by very high power, airborne laser systems in which size and weight are at a premium. In the Advanced RSR Modulator, significant size and weight savings result from the elimination of heavy and bulky components which make up the DC conversion portion of conventional modulators. This report summarizes the efforts in which groundwork was laid for the implementation of such a modulator for Air Force use. The achievements of this effort include 1 Production of a new 5,000 A pulse semiconductor switch, the T60R RSR, capable of blocking up to 1,200 V and repetitively switching an RMS current in excess of 250 A. 2 The development of the technology for applying the T60R in light weight, series switch assemblies capable of operating at integral multiples of 1,000 V operation through 5,000 V was demonstrated in the laboratory. 3 Demonstration of the feasibility of the AC resonant charge concept through operation of a 15-kW average power breadboard.
