An Energy Storage Test Power Supply Based on Fuzzy Quasi Proportional Resonance Control

This paper is devoted to designed a set of energy storage test power supply topology circuit based on phase-shifting transformer, energy storage capacitor and power electronic conversion device in order to provide a stable current source with fast control in the large-capacity type test of 10kV switchgear. A set of energy storage test power supply control strategy based on fuzzy quasi proportional resonance (QPR) control is designed. Finally, the simulation experiment is carried out on the MATLAB/Simulink experiment platform. The results show that this power supply can control the output waveform fast and accurately. And this power supply can provide the large current required for the short-time current withstand test of the switchgear.
