Abstract
A DC to DC converter circuit which accomplishes both non-pulsating input and output currents using a single simple coupled inductor is revealed. The DC to DC converter accomplishes either buck or boost conversion using a simple circuit requiring only two switches, one of which may be a simple diode rectifier, a capacitor, and two inductors, which may be colocated on a single common magnetic core. These converters are, in some ways, similar to the Cuk converter, but they do not provide inverted outputs. Zero voltage switching versions of these converters are revealed. Also revealed are techniques and methodology for reducing both input and output current ripple to near zero levels. The buck version of the circuit accomplishes DC to DC conversion without inversion and with no right half plane zero in its control to output transfer function. The boost version is also non-inverting.
