Analysis of Active Clamp Forward Converter of UAV

Abstract:

The Forward Switch mode power supply is good selection for power supplies of Unmanned Aerial Vehicle (UAV). Compared with the conventional forward converter, there is one auxiliary switch in the active clamp forward converter to recycle the energy stored in the transformer leakage in order to minimize the voltage stress of the main switch. The power system is designed and the operation characteristics of the active switching power supply are revealed by analysis a typical second-order system in this paper. Active Clamp Forward Converter reduce the generation of EMI, the EMC of UAV equipment is greatly improved. The results of the analysis are verified by SPICE simulation.
