Embodiment Construction
[0009] Below in conjunction with a preferred embodiment of the present invention and accompanying drawing, the present invention will be further described:
[0010] In this embodiment, the bridge output end of the rectifier circuit is connected to the high-frequency conversion circuit, the half-bridge output of the high-frequency conversion circuit is connected to the filter circuit, and finally the drive circuit is connected. like figure 2 As shown, the present invention first rectifies the alternating current, can add APFC power correction, then performs high-frequency conversion, can add frequency modulation and dimming to obtain high-frequency AC, and then filters through LC, and finally connects multiple driving circuits to drive multiple energy-saving lamps. as attached figure 1 As shown, transformer T1, C23, C24, and R27 form a filter circuit for alternating current, C23 and R27 are connected to terminals 1 and 2 of T1 in parallel, and C24 is connected to terminals 3...
