Abstract

The invention discloses a hard disk soft start power supply of a test mainframe. The hard disk soft start power supply comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a sixth capacitor, a first audion, a second audion, a third audion, a fourth audion, a diode, a voltage stabilizing diode and a potentiometer. The hard disk soft start power supply of the test mainframe consists of four audions. When the hard disk soft start power supply is used, output voltage of the first audion is gradually increased till rated voltage is reached, a motor works at the rated voltage to achieve smooth start, start current is reduced, and start over-current trip is avoided. When the motor reaches rated rotation speed, the start process is finished, the motor operates normally. By using the hard disk soft start power supply, the voltage is increased from zero to the rated voltage, and existing overload impact current is changed from uncontrollable to controllable. In addition, start current can be regulated according to the demand, and no impact torque exists in the whole motor starting process.

Description

technical field [0001] The invention relates to a starting power supply, in particular to a hard disk soft starting power supply of a test host. Background technique [0002] Software testing is to describe a process used to promote the correctness, integrity, security and quality of software identification. It is to operate the program under specified conditions to find program errors, measure software quality, and whether it can The process of evaluating to meet the design requirements, software testing is the process of using manual or automatic means to run or test a system, the purpose is to verify whether it meets the specified requirements or to clarify the difference between the expected results and the actual results, now Most of the hard disks in the stage test host are mechanical hard disks. The motor of the mechanical hard disk has a super high speed. At the same time, when the hard disk is powered on, the voltage increases instantly to drive the motor to rotate....
