Design of Low-voltage Power Supply Drive Circuit Based on the Piezoelectric Ceramic Transformer

摘要

The piezoelectric ceramic transformer has the advantages of high conversion efficiency, high pressure, electromagnetic compatibility, etc. It overcomes the shortcomings of large electromagnetic interference, low conversion efficiency, a large volume, etc. Using IR2184, the paper designs piezoelectric ceramic transformer full-bridge driver circuit. It greatly improves the conversion efficiency of the power system and power.
