  • Integrated power system capable of switching between power supply mode and electronic load mode and switching method thereof
    Patent number: 11901833
    Abstract: Systems and methods for switching between a power supply mode and an electronic load mode are disclosed. For switching from the power supply mode to the electronic load mode, the method comprises the steps of: deactivating a power element; activating a current control module and a phase-locked loop to obtain a voltage phase of a device under test; calculating a turn-on amount of the power element according to a current setting value and the voltage phase; and causing the power element to generate a load current for the device under test. For switching from the electronic load mode to the power supply mode, the method comprises the steps of: deactivating the power element; activating a voltage control module; calculating the turn-on amount of the power element according to a voltage setting value; and causing the power element to input a corresponding voltage to the device under test.
