ABSTRACT:
A bi-directional DC/DC converter includes a first switch coupled to a first input/output of the converter, a first input/output energy storage element coupled to the first input/output of the converter, a second input/output energy storage element coupled to a second input/output of the converter, an intermediate energy storage element coupled between the second input/output and the first switch and a second switch coupled to the intermediate energy storage element and to the first switch. A pulse width modulator operates the first switch between on and off states while the second switch is maintained in an off state to operate the converter as a buck converter, during which time the power is transferrred from the first input/output to the second input/output. A further pulse width modulator operates the second switch between on and off states while the first switch is maintained in the off state to operate the converter as a boost converter, during which time power is transferred from the second input/output to the first input/output.
