ABSTRACT OF THE DISCLOSURE A source V-A/load V-A differential converter (single quad- drant DC-DC topology) combines the canonical functions of both the boost and buck converter topologies. Basic advantages of the boost and buck topologies are retained, disadvantages of these and prior art compound topologies are eliminated, and several entirely new and useful functions are realized. These new func- tions include sub-microsecond source voltage/load step response (independent of feedback loop parameters), extremely wide source voltage range, very high conversion efficiency/power density, multiple auxiliary outputs with closely held voltage range para- meters (without resort to minimum load, pre-load, or sub-regula- tion), galvanic input/output isolation, enhanced capacitance safety/energy storage, reduced gain bandwidth requirements, and intrinsic stability. The differential term derives from the transfer function for this new compound topology, i.e., x=.delta.(a+x).
