Special bipolar linear voltage-stabilized source for software testing host

Abstract

The invention discloses a special bipolar linear voltage-stabilized source for a software testing host. The special bipolar linear voltage-stabilized source for the software testing host comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a sixth capacitor, a seventh capacitor, an eighth capacitor, a ninth capacitor, a tenth capacitor, a first three terminal regulator, a second three terminal regulator, a first amplifier, a second amplifier and a bridge rectifier circuit, the alternating current input end of the bridge rectifier circuit is connected with the electric supply, and the anode output end of the bridge rectifier circuit is respectively connected with the first end of the first capacitor and the input end of the first three terminal regulator. The special bipolar linear voltage-stabilized source for the software testing host uses two three terminal regulators to form a simple and practical symmetrical positive / negative voltage-stabilized source, the testing host is not influenced when the electric supply is changed suddenly, and the testing precision is guaranteed; the special bipolar linear voltage-stabilized source for the software testing host is simple, practical, stable, effective and broad in popularization and use value.

Description

technical field [0001] The invention relates to a bipolar stabilized voltage power supply, in particular to a bipolar linear stabilized voltage power supply dedicated to a software test host. Background technique [0002] Software testing is to describe a process used to promote the correctness, integrity, security and quality of software identification.

[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, it It is a software process that helps to identify the correctness, completeness and quality of computer software (whole or part) that has been developed (intermediate or final version); it is an important aspect of SQA (software quality assurance) Sub-domain, when the intermediate version of the developed software is tested on the test host, due to the imperfection of the software, it may cause the CPU and hard disk of the test host to overclock or run at high speed, and may also cause a sudden increase in power consumption of the test host. The change of voltage will affect the CPU and hard disk of the test host to varying degrees, which may lead to inaccurate tests
