Abstract: A DC to DC power supply including an energy transferring snubber circuit produces a changing magnetic flux by opening and closing a switching element to interrupt current flow in a first inductor. A current is induced in a second inductor in response to the changing magnetic flux. A first capacitor is charged with a current due to a first potential appearing across the switching element when the switching element is opened. The current induced in the second inductor and the current from the first capacitor is conducted to the load when the switching element is closed. A snubber circuit minimizes the first potential appearing across the switching element while transferring energy to the load.
