Patent ID: 8810275

Claim:
A method of dynamic impedance matching for improved transient performance in a direct current-to-direct current (‘DC/DC’) converter for delivering a load to an electrical component, the DC/DC converter including: a coupled inductor, wherein the coupled inductor receives a source input voltage level and outputs an output voltage level; a transient winding; and a variable impedance switch coupled to the transient winding, the method comprising: determining that a load to be delivered to an electrical component by the DC/DC converter has changed including determining an amount that the load to be delivered to an electrical component by the DC/DC converter has changed; and adjusting the impedance level of the variable impedance switch in dependence upon the change in the load to be delivered to the electrical component by the DC/DC converter, adjusting the impedance level of the variable impedance switch in dependence upon the amount that the load to be delivered to an electrical component by the DC/DC converter has changed.
