Patent number: 8797773Abstract: An isolated DC to DC converter including zero voltage switching and a current doubler. Current sensors are located between a positive input of the DC to DC converter and a current doubler is used in an output stage of the DC to DC converter in order to enable more accurate current sensing in a main transformer to prevent saturation of the transformer core and provide increased efficiency and power output with lower electromagnetic noise. The input of the DC to DC converter is isolated from the output of the DC to DC converter, and the DC to DC converter may be used in a hybrid or all-electric vehicle to provide an accessory bus from a power source of the vehicle.Type: GrantFiled: August 30, 2010Date of Patent: August 5, 2014Assignee: Cooper Technologies CompanyInventor: Mark Steven George

Patent number: 8659860Abstract: A power converter includes a transient voltage protection circuit connected between an input of the power converter and a power stage of the power converter. The transient voltage protection circuit provides a low resistance connection from the input of the power converter to the power stage of the power converter when the input voltage is less than a predetermined threshold, but blocks the input voltage from the power stage when the input voltage is equal to or greater than the predetermined threshold voltage. The power converter may be a boost power converter used in a vehicle to provide power from a main power bus of the vehicle to a subsystem of the vehicle such as an anti-lock brake system.Type: GrantFiled: July 14, 2011Date of Patent: February 25, 2014Assignee: Cooper Technologies CompanyInventors: Mark Steven George, Charles Lawrence Bernards
