Waveform Improvement Circuit Based on Bridge Rectifier Circuit

In recent years, with the development of information technology, a new uninterruptible power supply system (UPS) has emerged. The rectifier circuit is one of the most important modules of the UPS, and its wiring mode and waveform variation will affect the voltage and current of the output terminal. This topic first introduces the classification, principle and circuit diagram of rectifier circuits with many applications in modern power electronics technology, and the waveforms, advantages and disadvantages of different circuits have been analyzed [1], The principle, control method and process of the editable chip is used in the experimental part are discussed. Secondly, an improved circuit based on bridge rectifier circuit is designed. The parameter setting, wiring mode and control circuit turn-off value of the main circuit are analyzed. The variation of the output waveform of the improved circuit is verified by experiments. The rationality and reliability of the circuit is testified.
