Design of High Efficiency Single-Phase Bridge Passive Inverter Based on SG3525

Abstract

In this work, a method for simultaneously improving the conversion efficiency and power quality of marine distributed generation was proposed. Aiming at the insufficient correction of output waveform based on inverter technology, a model of improved inverter conversion system was built. For the limitation of external power grid pollution treatment, the self-regulation ability of the output voltage waveform was improved by adding high-performance real-time feedback technology and PI regulation. The test results showed that the proposed method had the advantages of stable output, high precision, good power quality, and superior to the traditional method of indiscriminate feedback regulation in terms of power conversion efficiency.
