Each primary coil connects a full-bridge circuit comprising two switches on two legs, the primary coil being connected between the switches on each leg, each full-bridge circuit being connected in parallel wherein each leg is disposed parallel to one another, and the secondary coils connected to a rectifying circuit. An outer loop control circuit that reduces ripple in a voltage reference has a first resistor connected in series with a second resistor connected in series with a first capacitor which are connected in parallel with a second capacitor. An inner loop control circuit that reduces ripple in a current reference has a third resistor connected in series with a fourth resistor connected in series with a third capacitor which are connected in parallel with a fourth capacitor.application/pdfen-USMultiphase soft switched DC/DC converter and active control technique for fuel cell ripple current eliminationPatenthttp://pimg-fpiw.uspto.gov/fdd/86/188/075/0.pdf11249945363/17363/65363/71H02P8/127518886
