PLANAR LIGHT-SOURCE PULSE-TYPE DRIVING CIRCUIT ADOPTING A TRANSFORMER

摘要

A planar light-source pulse-type driving circuit adopting a transformer is provided to improve power consumption and photonic efficiency, so realizing high voltage pulse type driving inverter having the small conduction rate through simple configuration. In a planar light-source pulse-type driving circuit adopting a transformer, the secondary winding is combined with the both terminals of the power source of the surface light source(10). A transformer supplies the driving voltage to the surface light source(Tx). More than one capacitor(C1) is operated as a voltage source. More than one switch(S1, S2) converts voltage outputted to the input voltage source(Vcc) into a pulse. A diode module includes more than one diodes(d1, d2), and more than one inductor passes current supplied to transformer or current outputted to the transformer(L1).
