| Summary: | 碩士 === 國立臺灣科技大學 === 自動化及控制研究所 === 104 === By using LabVIEW (Laboratory Virtual Instrument Engineering Workbench), this thesis designs an automatic measurement and reporting system and applies it to the stability testing of a DC-DC converter.
Generally, in the earlier design, the DLL file is used to drive electronic devices with Sequence Structure and Event Structure. However, in our studying, the Virtual Instrument Software Architecture (VISA) is use to drive the equipment and devices. The main structure of this software is based on Master & Slave mode. It also uses the Event Structure, State Machine, and Queue to program the software. Moreover, the hardware equipment and devices are connected to each other through GPIB as their interface. The design of this thesis include 13 different automatic testing items, and all of the reports can be generated automatically. The designed testing items include: Ripple, Transient, Drain, Source, Gate waveform of MOSFET, Switching Frequency, Jitter, Overshoot at Turn on and Undershoot at Turn off, Turn on/off sequence, Efficiency, Current Balance in Multi-Phase, Over Current Protection (OCP), Short Circuit Protection (SCP), Over Voltage Protection (OVP), and Under Voltage Protection (UVP).
Through this auto-test and auto-report-generating system, and with the proper design targets of DC-DC converter, the accuracy and stability of the converter will be revealed by the extremely fast and highly efficient design. With the friendly and intuitive LabVIEW interface environment, and based on different demands, the users are not only able to operate easily but also able to program easily. This auto-test system will greatly improve the working efficiency by greatly reducing the human test and human report generating time.
