A power conversion circuit

The present invention is applicable to the field of power supplies, there is provided a power conversion circuit, the circuit comprising: a power conversion unit for converting a first power supply voltage required by the load of the first or the second output voltage of the second load required output voltage; first feedback unit, according to a first variation of the output voltage of the power conversion control unit adjusts the output voltage, the first feedback means having a first parameter; second feedback means for controlling the output voltage according to a change of the second power converter means to adjust the output voltage, the second feedback unit has a second parameter; a first control unit for selecting the first or second load means regulate the output voltage of the first or second feedback means feedback. The present invention, when the load changes, the control unit by feedback means having different parameters to adjust the output voltage value of the power converter to meet the needs of different load, without changing the circuit configuration, the circuit configuration is simple, high stability, low cost.
