Adaptive control of converters is provided to achieve, in one case, a constant current characteristic by controlling input power as a function of the ratio of output voltage to output current. In another class of circuits, input current to the converter is controlled under an adaptive control arrangement in response to output voltage/output current ratios which may also be modified by input current or input voltage. The adaptive control may be augmented with low frequency negative feedback control loops.
