Description: |
| 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.
Claim:
A zero-voltage-switched multiresonant converter for generating a regulated DC output voltage for supply to a load from a DC input voltage provided by a DC voltage source, comprising: a first transistor switch connected in series with said DC voltage source and said load; a second transistor switch connected in parallel with said DC voltage source and said load; a first capacitor connected in parallel with said first transistor switch; a second capacitor connected in parallel with said second transistor switch;
a first inductor connected in series with said DC voltage source, said load and both of said first and second transistors switches; means coupled to the gate of said first transistor switch for controlling switching of said first transistor switch as a function of the input voltage provided by said voltage source to said converter for stabilizing the current through said first inductor; and means coupled to the gate of said second transistor switch for controlling switching of said second transistor switch as a function of the output voltage of said converter. |
