<p>A DC to DC power converter (22) and a method for boosting and bucking an input voltage (Vs) are disclosed. The DC to DC power converter includes one or more output converter stages electrically coupled to an input voltage source through an inductor (24). Each output converter stage comprises a capacitor (40, 42, 44) and at least two switches (46, 48, 50, 52) for switching at a desired duty cycle in an ON stage and an OFF stage for generating an applied voltage, such that the input voltage source (12) continuously delivers power to a load (26) and the capacitor. The one or more output stages enable a DC to DC voltage conversion to any desired step -up ratio or step -down for the output voltage. In another embodiment, output converter stages are switched such that bidirectional power flow is achieved.</p> |
