Abstract
An apparatus (100) includes a buck and boost conversion circuit (110), and a control unit (120, 200) for controlling operations of the buck and boost converter. The buck and boost converter includes a buck conversion circuit having a first set of switches (SW3, SW4), and a boost conversion circuit having a second set of switches (SW5, SW6). The buck conversion circuit and the boost conversion circuit may be controlled independently from each other. The control unit is configured to control delivery of power from the power converter to a load (20) via the buck conversion circuit in a buck conversion mode by controlling switching operations of the first set of switches, and to control the delivery of the power from the power converter to the load via the boost conversion circuit in a boost conversion mode by controlling switching operations of the second set of switches.
