Patent ID: 7579814

Claim:
A power converter comprising two input terminals, two output terminals, an output capacitor coupled between the two output terminals, a first inductor in a series path between the input and output terminals, a switch controlled by a control signal, and a first diode, the converter having a configuration for producing an output voltage at the output terminals from an input voltage supplied to the input terminals, the converter further comprising a second inductor, a resistor connected in series with a second diode, the series-connected resistor and second diode being connected in parallel with the second inductor, the second inductor and the series-connected resistor and second diode in parallel therewith being in a path in series with the switch and the first diode, and a capacitor connected in parallel with the first diode, or in parallel with a series connection of the first diode and the second diode, or in parallel with a series connection of the first diode and the resistor.
