ABSTRACT:
A multiresonant DC to DC converter which operates at a substantially fixed frequency yet maintains relatively constant efficiency levels despite wide variations in input voltage. The multiresonant converter includes a first transistor switch in series with the DC voltage supply source and the load and a second transistor switch in parallel with the DC voltage supply source and the load. The switching action of the first transistor switch is controlled as a function of the supply voltage input to the converter while the duty factor of the second transistor switch is controlled in accordance with the output voltage of the converter.
