In the Figure, FU is fuse. C1, C2 are the bulk capacitors. C3, C4 are the starter capacitors. VD1, VD2, VD3, VD4 are the rectifier diodes. R1, R2 are the current limiting resistors. H is fluorescent tube or energy saving lamp. Before H turns on, the internal resistance is great, and the current is very low, and the power is added to the rectifier circuit composed of VD1 ~ VD4. C1, C2 choose the 1.5μ F capacitors with voltage in more than 400V. C3, C4 choose 0.01μF capacitors with voltage in more than 400V. VD1 ~ VD4 choose 1N4007 1A silicon rectifier diodes with voltage more than 400V. R1, R2 select 5W metal film resistors with more than 50 ~ 100Ω.
