POWER CONVERTER FOR GENERATING BOTH POSITIVE AND NEGATIVE OUTPUT SIGNALS

摘要

A power converting system produces an input signal regulated with respect to an input signal. The power converting system has a first inductive element having a first node coupled to an input node, and a second inductive element having a first node coupled to an output node. A first switching element is coupled to a second node of the first inductive element. A first capacitive element is coupled between the second node of the first inductive element and of the second inductive element. A control circuit sets a duty cycle of the first switching element to a first value for providing the output signal of a first polarity responsive to the input signal of the first polarity, and to set the duty cycle of the first switching element to a second value for providing the output signal of a second polarity responsive to the input signal of the first polarity.
