2018 Electronic Competition Question E-Energy Recovery Device (Xidian University)

Outstanding works of e-sports competition in 2018

Overview

Design and produce an energy feedback device for the converter and load test. This work uses SPWM modulation to achieve unipolar inversion. At the same time, dead zone control and soft start are added. The unipolar efficiency reaches more than 90%. In order to prevent The influence of the downstream load on the inverter waveform is corrected by power factor at the subsequent stage. After correction, the power factor reaches above 0.95, and the voltage is further increased and stabilized. Finally, through a push-pull topology switching power supply, the same as the previous stage is achieved. level isolation, and at the same time implemented constant current control, taking into account the simplicity of the system and the efficiency of the power supply to meet the requirements of the topic.
