Abstract

The invention provides a power supply adjusting circuit, an adjustable power supply system and a method thereof. The adjustable power supply system comprises a power supply module, a device power supply and a control circuit. The device power supply executes power supply operation according to the working voltage and provides a power supply for a device under test (DUT). The control circuit outputs an adjusting signal to the power supply module according to the power utilization condition of the device to be tested. The power supply module generates a working voltage according to the adjusting signal, and enables a first power consumption generated by a power supply of the device to be smaller than a preset power. Therefore, the device power supply can provide high voltage and high current output for the to-be-tested device.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply adjustment circuit, an adjustable power supply system and a method thereof. Background technique [0002] see figure 1 Schematic diagram of the power supply for the device under test, figure 1 Most of the existing Device Power Supply (DPS) 10 can withstand a maximum power consumption of about 10W. However, in order to meet the high current demand of the device under test 12, the operating voltage VDD of the device power supply 10 can be set at 10V , and the device power supply 10 can stably provide a supply voltage of -1V to 7V and a supply current of 0.7A to the device under test 12 . Although the device power supply 10 can withstand a certain amount of power consumption, as the power consumption of the device power supply 10 increases, the temperature of the device power supply 10 will also increase, so the device power supply 10 must be treated with a heat dissipation ...
