Abstract
The present invention provides a circuit system of switching-type power converter having dual DC output stages. The circuit system comprises: a DC power supply which supplies the power needed by the circuit system of switching-type power converter dual DC output stages; a first DC/DC converter coupled to the power supply circuit and converting the power outputted from the DC power supply into a DC output voltage, in which the DC/DC converter at least comprises a switching element; and a second DC/DC converter coupled to the DC power supply and connected in parallel with the first DC/DC converter, and converting the power outputted from the DC power supply into another DC output voltage, in which the second DC/DC converter shares the switching element with the first DC/DC converter.
