Design and Application of Inverter Efficiency Test System Based on LabVIEW

In order to enhance automaticity of inverter efficiency test, an inverter efficiency test system developed with LabVIEW software is designed. the test system can realize the communication between computer and programmable DC power supply via GPIB, and can complete parameter settings and output control of DC power supply. Eventually, output control of inverter is reachable. An experimental verification has been done, which shows that this system runs stably, and certain practicability is available.
