Floodlight power failure self-lock switch circuit

Published:2011/4/22 19:21:00 Author:Nicole | Keyword: floodlight, power failure, self-lock switch

The floodlight is controlled by a ordinary stayguy switch, if it is power failure, it will be hard to differentiate whether the light is off, after it has power, the light will turn on all night, it is a waste of energy. If using this circuit to replace the ordinary stayguy switch, it will avoid this shortage, because it can beself-locked, the light will not be turned on. VTH should depend on the floodlight power, generally, it can use BCR3AM small plastic package TRIAC(3A/600V).   (View)

Changing the output voltage of ringing switching power supply circuit diagram

Published:2011/4/22 18:45:00 Author:Nicole | Keyword: switching power supply

In the ringing choke type switching regulator circuit, the output voltage Uo is in direct proportion to the negative bias Uc, in order to change the output voltage, we should find a way to change Uc, as shown below. The collector of transistor VT2 is connected on the negative terminal of capacitor C2. Once Uc2 increased, the base current of Zener diode VD2, transistor VT2 also increase, so that VT2 conducting. Because of the collector current VT2 can shorten the conduction time of switching transistor VTl than before, so it can be ended early, then to bring down the output voltage Uo.   (View)
