PIEZOELECTRIC RESONANT CIRCUIT OF LAMP LIGHTING

摘要

FIELD: electricity. ^ SUBSTANCE: resonant circuit uses own capacitors of a piezoelectric transformer as piezoelectric capacitors. One lamp is connected to one group of piezoelectric capacitors. Several groups consisting of piezoelectric capacitors and a resonant throttle are connected in parallel or serially to produce a parallel resonant circuit of lamp lighting or a cascade resonant circuit of lamp lighting. In case several lamps are used for lighting, there is a fixed frequency provided to achieve fixed input complete resistance of substitution circuits of piezoelectric capacitors. ^ EFFECT: higher reliability and efficiency of lamp lighting, reduced leakage current and lower heating. ^ 18 cl, 15 dwg
