Problems solved by technology
The existing DC linear regulated DC power supply has the advantages of lower output voltage than input voltage, fast response, small output ripple, and low noise generated during work; Or the operation mode of basically continuously adjusting the AC voltage value at one time, and the temperature sensor is not installed on the main parts, resulting in the inability to detect the temperature changes of the parts in time during the operation, and it is very easy to automatically stop the operation after the parts are overheated. The use performance is greatly reduced, and the adjustment of the AC voltage value in different positions or basically continuous one-time adjustment cannot guarantee that the adjustment is completely in place, and the voltage difference value of the voltage regulator adjustment tube varies in a large range, resulting in an increase in the power consumption of the adjustment tube , thereby increasing the area of the radiator and increasing the number of adjustment tubes used, resulting in an increase in use loss and reduced service life. At the same time, energy consumption is also increased, which cannot achieve energy-saving effects and indirectly reduces environmental protection performance.
