Smart Adaptive Power Converter Control

"Mide is proposing to develop an adaptive mixed-signal controller for DC-DC converters. The controller will use adaptive control algorithms to enhance total system performance of switching DC-DC converters. The innovative concepts include: 1) digitalimplementation of feedback and feedforward 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. Phase II will generate designs and validate these designs using breadboarded hardware. The adaptive controller will use ahigh power-density state-of-the-art DC-DC converter as baseline. This converter design will be examined to identify modifications needed to space qualify the design. Phase II will perform risk-buy-down elements of the space qualification test program andit will also design a mixed signal ASIC."
