This report gives the results of all Program tasks for the Advanced Inverter Technology Program. APL has three existing series resonant inverter-based power converters. The control and protection circuits are different for the three units. The purpose of this program was to produce a control and protection architecture and functional circuits that would work with all three power stage topologies. The requirements for the three existing power stages were determined. The three existing control and protection circuits were analyzed. An IC technology study was performed to determine the optimum technology and fabrication method for SRI control and protection circuits. A control and protection architecture utilizing common functional circuits that would work with the three existing topologies as developed and block diagrams drawn. The functional tasks were partitioned into five custom parts. The requirements for the custom parts were described. A study was performed to assess the potential present and future functions for a microprocessor in a series resonant inverter. A packaging and thermal study was performed to investigate the problems associated with space deployment of a 200-kW series resonant inverter. Keywords include Control Architecture, Converter Control, Converter Protection, Gate Control, Generalized SRI Control and Protection, Power Converter, and Series Resonant Inverter Control.
