Low-voltage Automatic Switching Circuit

Published:2011/5/7 3:02:00 Author:Joyce | Keyword: Low-voltage, Automatic, Switching

Low-voltage Automatic Switching Circuit is shown in the graph below.When the electric supply of 220V is depressurized by transformer T, VDw will breakdown thus making VT1 breakover and VT2 cut off.Meanwhile,the solid-state relay SSR will shutoff.At this time, after being bridge rectified by VD2 ~ VD5 andfiltered by C2.C3,it will output about 14V dc voltage. When the input ac voltage is 110V, after being depressurized by T, it is insufficient to breakdown VDw,so VT2 will breakover and VT1 will cutoff and SSR will be connected. At this moment, SSR, VD2 ~ VD3 and C2 、C3 will constitute a voltage doubling circuit ,which still output about 14V dc voltage. And the LED indicator light will be on.   (View)

555 IC automatic battery charger circuit diagram(1)

Published:2011/5/9 20:38:00 Author:Ecco | Keyword: 555 , IC , automatic , battery charger

Automatic nickel-cadmium battery charger circuit is shown as the chart, the charger is mainly composed of the power supply circuit, voltage comparator and indicating circuit. The power supply is stepped-down by the T transformer, rectified by diodes VD1 ~ VD4, stabilized by three-terminal voltage regulator Manifold A1 and filtered by capacitors C1, C2, then the circuit can output stable 9V DC voltage for the charger. Voltage comparator is composed of A2 time base circuit, and it has a Zener diode VS (stable voltage 5.6V) connected to pin 5 of the control side, so the reset level of the circuit will be located in the 5.6V. VL LED is the charging indicator. A1 selects LM7809 three-terminal voltage regulator Manifold, and it should be installed aluminum heat sink. VD1 ~ VD5 use IN4001 silicon rectifier diodes. VS selects 5.6V, 1/2W Zener diode, such as UZ-5.6B, IN5232. VL uses an ordinary red LED. RP selects 2W wirewound potentiometer, R1 ~ R4 are select 1/8W carbon film resistors. C1 selects CD11-25V aluminum electrolytic capacitor, C2, C3 are the CD11-16V aluminum electrolytic capacitors. S uses an ordinary small 1 × 1 power switch. T uses 220V/12V, 5VA small, high quality power transformer.   (View)

Relay-composed Start-up Circuit

Published:2011/5/7 3:23:00 Author:Joyce | Keyword: Relay-composed, Start-up

Relay-composed Start-up Circuit is shown in the graph below. In the input end of the power ,resistance R is connected.R has two functions.the first oneis that it can prevent impluse current on the large capacitance C1 in starting up,which wouldimpact the poweritself;the second one is to prolong the time when the load is receiving the electric supply. In this process, because the voltage of the relay J in the output end is less than 12 V ,the actuation voltage, R will be connected to the circuit to limit the current and depressurize the voltage.As the charging of C1, C3 completes, relay J contacts and actuates to short-circuit R. At this moment, power supply will function properly.   (View)
