Abstract

The invention discloses a device internally including a plurality of isolated temperature control detection units. The device comprises a plurality of isolated temperature control detection units, a feedback signal selecting device, an output voltage control device, and a voltage adjuster. The isolated temperature control detection units are arranged at a plurality of positions, so as to conduct the temperature monitoring detection and integrate the monitored and detected temperature data with a signal, thereby enabling the signals of the isolated temperature control detection units, such as (T1) and (T2)...(TN), to be converted into output signals containing temperature information, such as (F1) and (F2)... (FN); the feedback signal selecting device is used for receiving the signals, (F1) and (F2)...(FN), which are output by the isolated temperature control detection units, and choosing a signal with the maximum temperature from the signals, such as (F1) and (F2)... (FN), to be output; the output voltage control device is used for receiving the signal with maximum temperature output by the signal selecting device and a voltage feedback signal, and outputting a control signal; and the voltage adjuster is used for receiving the control signal output by the output voltage control device and outputting a voltage used for controlling the speed of the fan.

Description

technical field [0001] The invention relates to an instrument device, in particular to a device with multiple sets of isolated temperature control detection units. Background technique [0002] Instruments or devices related to AC and DC power supply (AC / DC Source) provide convenience for power electronics R&D personnel to simulate various power supply states, power waveform distortion, and measure and analyze power characteristics, and can provide correct and effective test solutions to Simulate various normal or abnormal power supply phenomena, and measure and analyze them at the same time. The integrated power supply test and analysis equipment is fully suitable for R&D characteristic analysis, production test, product quality inspection or automation system integration. [0003] In this product, power loss occurs when the switching converter operates, and most of the power loss is dissipated in the form of heat. Therefore, a fan is necessary for the converter, especially...
