Development of LabVIEW Models for Resonant Power Converters

Inhalt:
The aim of this paper is to present the modeling of electronic energy converter in the popular development system LabVIEW(r). Using the various extensions and hardware capabilities it allows an intuitive, easy and comfortable way to examine, study and prototype these kind of devices. Two types of devices are investigated: with an alternating current output – full-bridge resonant inverter with reverse diodes and with a direct current output – series full-bridge resonant DC-DC converter. In the formalization and analysis of the power circuit are used interconnected parameters, which describe the behavior and operational regimes. The models are verified using the specialized simulation software LTSpice IV and data from laboratory experiments.
