Patent ID: 8363427

Claim:
A bi-directional DC to DC converter comprising: a first resonant tank circuit employed during power transfer along a first direction through the bi-directional DC to DC converter; and a second resonant tank circuit employed during power transfer along a second direction through the bi-directional DC to DC converter, wherein the second direction opposes the first direction and wherein the first resonant tank circuit shares at least two common resonant components with the second resonant tank circuit, the at least two common resonant components comprise a capacitor connected in series with an inductor, and the first resonant tank circuit further comprises a first resonant component that is different from a second resonant component comprised by the second resonant tank circuit, the first resonant component comprises a first inductor connected in series with the at least two common resonant components and the second resonant component comprises a second inductor connected in series with the at least two common resonant components.
