1. A power source apparatus, comprising:

  • a power source voltage input terminal connected to an external battery;

    an insulating transformer, comprising a primary-side coil connected to the power source voltage input terminal;

    processing circuitry connected to the power source voltage input terminal, and the processing circuitry being configured to measure an input voltage to the power source voltage input terminal;

    a power switch connected to the processing circuitry;

    a transmitter configured to transmit a voltage value measured by the processing circuitry to a secondary side of the insulating transformer;

    a switch, configured to control a time for applying a voltage to the primary-side coil; and

    a controller configured to control the switch, whereinthe processing circuitry is further configured to perform a power-off control on the controller when the voltage value is not within a given range, and whereinthe processing circuitry comprises a non-volatile memory for storing a first power state flag or a second power state flag, wherein the first power state flag corresponds to a power-on control on the controller, and the second power state flag corresponds to the power-off control on the controller;

    when the processing circuitry is activated by the input voltage and detects the first power state flag from the non-volatile memory, the processing circuitry executes the power-on control on the controller,when the processing circuitry is activated by the input voltage and detects the second power state flag from the non-volatile memory, the processing circuitry enters a standby state for detecting a press of the power switch, andwhen the press of the power switch is detected in the standby state, the processing circuitry executes the power-on control on the controller.
