Solar array switching unit (SASU) technology is an attractive candidate for output power regulation of solar arrays. It offers greater efficiency, lower parts count, modularity and expandability. Since the SASU has switching frequencies upwards of 15 kHz, it was necessary to determine the performance characteristics of the SASU with a real solar array and to assess the impact of long lead lengths on the switching characteristics. To accommodate these requirements, TRW developed a 10 kW, 120 volt SASU which was tested for steady state and transient resistive and converter type loadings. The SASU met or exceeded performance expectations. No noticeable variation was observed in the output voltage regulation for changes in load.
