| Abstract: | A movel two amplitude DC link current control strategy for Series Actively Clamped Resonant DC link Inverter(SACRLI)is proposed.It inherits the simplicity of traditional topology and obtains Zero Current Switching(ZCS)condition for all the devices.The greatly reduced power dissipation on the resonant link and extended high frequency operation potential are achieved by the imported scheme.Therefore the outstanding performance of the inverter is available.In this paper,detailed operation process is analyzed and critical condition to realize two amplitude resonance is discussed.Comparison between the proposed control technique and the traditional one is made to show the improved performance.Simulation and experiment verified the effectiveness of the proposed control technique. |
