AbstractMide is proposing to investigate the use of adaptive control algorithms to enhance total system performance of switching power amplifiers and converters, with intended implementation in a radiation hard dc-dc converter. Mide is also proposing toinvestigate the area of component adaptation in these systems, with the focus on the use of variable power reactances, and adaptive rectifiers (variable V-I characteristic for semiconductor switching devices). The innovative concepts include: 1) digitalimplementation of feedback and feed-forward power controllers for high frequency switching amplifiers, permitting load dependent tuning of controller operation 2) extension of synchronous rectifier concepts to allow power MOSFETs to achieve wider range ofterminal characteristics to assist in converter adaptation 3) investigation of variable power reactances for converter adaptation.In Phase II Mid¿ will develop/design and
