Advanced Inverter Technology.
Abstract
APL has three existing series resonant inverter-based power converters: Power--10kW, 5kW, 200kW, Topology--dc/dc 1/2 Bridge, ac/dc Full Bridge, dc/dc Dual Full Bridge, 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 exsiting 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 was developed and block diagrams drawn. The functional tasks were portitioned 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. Packaging and thermal study was performed to investigate the problems associated with space deployment of a 200-kW series resonant inverter. Recommendations for control and protection architecture, functional circuits, parts selection, and fabrication as hybrid circuits are made.
