1. A method of providing power to a load, the method comprising:
providing a switching regulator having a regulator input connected to receive power from a source and a regulator output for delivering a controlled voltage, Vf, to a factorized bus, the switching regulator having a regulator response time, Treg;
providing a current multiplier stage having switching power conversion circuitry constructed and arranged to convert power received from the factorized bus via an input at an input voltage, Vin, for delivery to a load via an output at an output voltage, Vout, using a voltage transformation ratio, K=Vout/Vin, that is constant, based on an equivalent output resistance, the current multiplier having a multiplier response time, Tm;
providing an accelerator circuit having an output connected to supply current to the factorized bus, the accelerator having an error input connected to detect perturbances in the output voltage, Vout, the accelerator responsively supplying current to the factorized bus, the accelerator having an accelerator response time, Tacc;
wherein the accelerator response time, Tacc, is shorter than the regulator response time, Treg.
