US 2025/0060710 A1 · AC POWER SUPPLY CAPABLE OF PROGRAMMING OUTPUT IMPEDANCE AND A METHOD FOR SIMULATING OUTPUT IMPEDANCE

Abstract

The present invention provides an AC power supply capable of programming output impedance and a method for simulating output impedance. The method comprises the following steps. The simulating command, selectively provided by a control circuit, is associated with a voltage adjustment value and a phase adjustment value of a test circuit. The control circuit calculates the voltage adjustment value and a preset voltage value to form a voltage command, and calculates the phase adjustment value and a preset phase value to form a phase command. A power supply circuit generates a simulated output voltage according to the voltage command and the phase command. The preset voltage value and the preset phase value are related to a preset output voltage provided by the power supply circuit, and the simulated output voltage is a simulation of the preset output voltage, provided by the power supply circuit, passed through the test circuit.
