ABSTRACT:
A voltage converter whose output voltage is determined by the duty cycle of at least one switch and which includes ripple steering circuitry, and a current source whose output current is determined by the duty cycle of at least one switch and which includes ripple steering circuitry. In some embodiments, the voltage converter includes at least one yoked switch pair, circuitry for controlling the duty cycle of the yoked switch pair, and ripple steering circuitry. Preferably, the voltage converter includes a transformer, an input side, an output side, and ripple steering circuitry implemented on the input side. Examples of voltage converters in the first class are forward converters, flyback converters, and full bridge forward converters. In other embodiments, the invention is a half bridge voltage converter, which includes a transformer, an input side, an output side, a first branch on the input side (including a first switch, at least a first capacitor, and a primary winding of the transformer), a second branch on the input side (including a second switch, at least a second capacitor, and the primary winding of the transformer), control circuitry for controlling the duty cycle of each of the switches, and ripple steering circuitry on the input side. In other embodiments, the invention is a SEPIC voltage converter including a transformer, an input side, an output side, a switch on the input side, control circuitry for controlling the duty cycle of the switch, and ripple steering circuitry on both the input side and the output side.
