Abstract:
A power converter apparatus comprising:an input port; an output port; a first inductor coupled to the output port; a first switching circuit coupled to the input port and the first inductor, the first switching circuit operative to repetitively perform a cycle comprising a first state in which the first switching circuit couples the first inductor to the input port such that energy is transferred from the input port to the first inductor, a second state in which the first switching circuit short circuits the first inductor, and a third state in which the first switching circuit decouples the first inductor such that energy is transferred from the first inductor to the output port; a second inductor coupled to the output port; and a second switching circuit coupled to the input port and the second inductor, the second switching circuit operative to repetitively perform a cycle comprising a first state in which the second switching circuit couples the second inductor to the input port such that energy is transferred from the input port to the second inductor, a second state in which the second switching circuit short circuits the second inductor, and a third state in which the second switching circuit decouples the second inductor such that energy is transferred from the second inductor to the output port.
