| 摘要 |
<p>The present invention relates to an isolated driving circuit comprising an isolated driving transformer, a double-end excitation signal driving and controlling circuit and a pulse-driving signal conversion circuit, wherein the double-end excitation signal driving and controlling circuit is used for generating a first pulse driving signal and a second pulse driving signal; and the pulse-driving signal conversion circuit is used for converting an output signal of a secondary winding into a driving signal which is used for driving a corresponding power switching tube. The isolated driving circuit provided by the present invention can avoid resonance oscillation caused by the magnetic inductances of a blocking capacitor and a driver transformer.</p> |
