As the figure shows, when the S1 and S2 are closing, the light E lights normally; when the S1 is in the closing state, and the S2 is opening, the light E outputs the dark light; if you open S1, the light E will turn off no matter the S2 is opening or closing.

When the convertor of the electric car charger is working in the high frequency state, it will cause the harmonic pollution to the power grid, so we must do some effective actions to limit the total harmonic quantity of the electric car charger's convertor. For now, the charging converter must meet the IEEE519-1992 standard or the similar standards. To meet these standards, the charging converter can use the single stage or two stage PFC circuit and the integrated charger. To further improve the conversion efficiency, we can use the soft-switching circuit in the high frequency condition to reduce the power consumption of the switch tube.

Published:2011/6/27 2:59:00 Author:TaoXi | Keyword: Simple, four stages, light changing, switch circuit
The simple four stages light changing switch circuit is as shown in the figure, it has four stages of luminance combination: when the switches S1, S2, S3 are all closing, light E is the brightest; when the switches S1 and S3 are closing, the light E is in the bright state; when the S1 and S2 are closing, and the S3 is opening, the light E is in the dark state; when the S1 is closing, the S2 and S3 are opening, the light E is in the darkest state; if S1 open, the light E will turn off. L can be used as the inductance of the 20~40W fluorescent ballast, the power of E can not exceed 60W.

Published:2011/6/27 3:56:00 Author:TaoXi | Keyword: Lighting indication, light switch circuit
The lighting indication light switch circuit is as shown in the figure, when the switch S is opening, the 220V AC current is reduced and limited by the resistance R, then it adds to the two ends of the LED with the bulb E, so the LED has power to turn on. We can find the switch at night. At this point the current which flows through E is very small, it is only 2mA, we can consider that it has no power consumption, the light will not turn on. If you close the S, the bulb E can shine normally, at this time the LED turns off. If you open S, and the LED will not shine, this means that the filament of bulb E has burned off or the power grid has cut off.
