Abstract
The present invention provides an output voltage compensation method, for a DC voltage source having a constant voltage circuit and a constant current circuit connected in series, and the DC voltage source provides an output voltage to a device under test (DUT), and the output voltage compensation method comprising: generating a voltage compensation value according to a load current and a gain parameter of the DUT; generating a virtual current setting value according to a voltage setting value and the voltage compensation value; generating a duty cycle command according to the virtual current setting value and a load current measurement value of the load current; and generating the output voltage conforming to the voltage setting value according to the duty cycle command. Wherein the gain parameter is related to a multiplier parameter of the constant voltage circuit.
