Abstract
An adapter device for test, including: an adapter board having a voltage input terminal connected to an external power supply and an output terminal connected to a terminal to be tested; a voltage conversion circuit disposed on the adapter board and connected to the voltage input terminal and configured to convert the voltage of the external power supply received at the voltage input terminal into a test voltage to be supplied to the terminal to be tested; a feedback circuit connected to the voltage conversion circuit and configured to compare the test voltage with a reference voltage to provide feedback data; and a compensation circuit connected to the feedback circuit and the adapter board, and configured to generate a compensation voltage based on the feedback data and apply the compensation voltage to the adapter board to compensate for the test voltage.
