Abstract

A open-loop LCC resonant sine-wave inverter with fixed transformation ratio is discussed in this paper. The inverter is made up of a full-bridge switch circuit, the LCC resonant tank unit and a transformer which provided multi-outputs from its secondary windings. The gain and harmonics of the open-loop inverter under different load conditions are analyzed in detail. The soft switching characteristic of the full-bridge transistors under resonant mode is also discussed in this paper. According to the parameters and components given by the prototype, the stability of open-loop gain is calculated as the temperature range from -55°C to 70°C. Finally, the stability of open-loop gain is verified by Saber simulation and the prototype experiment.
