Abstract
A ceramic transformer level driving circuit mainly aims to transform a low voltage signal to another low voltage signal through an amplified signal to drive a medium voltage system. It includes a control unit to generate a resonant frequency and output phase signal waveforms, a waveform transformation unit to provide phase signals and perform waveform phase transformation for the phase signal waveforms, and a medium voltage driving circuit which includes a floating level unit and a driving unit which receives a medium voltage electric input. The driving unit actuates opening and closing at different time to enable the floating level unit to output a voltage floating level thereby to drive a ceramic transformer to control the medium voltage system through a low voltage level.
