1. a kind of device that solder type electric power is provided, including:

  • Input circuit, for receiving the ac input voltage with the first amplitude in the range of ac input voltage, and generates firstD/C voltage;

    Boost converter, is configured as receiving the first D/C voltage and exports with the first amplitude independent of ac input voltageSecond D/C voltage of fixed amplitude;

    Output circuit, is configured as receiving the second D/C voltage and the second D/C voltage is converted into solder type electric power;

    Dc-dc is controlled, is configured as receiving the first D/C voltage and output control electric power signal is as the 3rd D/C voltage;

    Boost converter control unit, believes for receiving control electric power signal and generating the control for the operation for controlling boost converterNumber;

    AndAC power supplies is aided in, for receiving the second D/C voltage from boost converter and generating AC auxiliary output voltages.
