Abstract:
1. A switching bidirectional power converter to efficiently convert power comprising: an inductor coupled between a first main terminal of said power converter and a switching node; a first power device coupled between said switching node and the negative terminal of said power converter; a second power device coupled between said switching node and a second main terminal of said power converter; a first feedback network to generate a first synthetic ripple signal when said power converter operates as a step up converter; a second feedback network to generate a second synthetic ripple signal when said power converter operates as a step down converter; a comparator providing hysteretic control of said power converter in response to said first and second synthetic ripple signals, to a reference signal, and to a mode selection signal; a control logic circuit and a pre-driver circuit for generating the signals to drive said first and second power devices in response to the output signal of said comparator.
