NE556 automatic monitoring circuit of starting battery of dynamo

Published:2011/6/20 6:22:00 Author:chopper | Keyword: automatic monitoring, starting battery, dynamo

This is a automatic monitoring circuit of starting battery of dynamo,and it can detect the voltage state of storage battery continuously.When the battery discharges to the prescriptive lowest voltage,it will stop charging automatically;when the battery needs a charger but the charge power supply is not available,it can distinguish automatically and send out a acoustic signal to remind operating staff of power supply.In addition,it has a function of automatic-manually operation convertion,which makes it charge the battery at any time manually.   (View)

printed circuit board with enough creepage distance in the high voltage circuit

Published:2011/6/15 5:13:00 Author:chopper | Keyword: printed circuit board, creepage distance, high voltage circuit

In the power supply circuit,there should be enough interval among lines for security.The interval is usually called creepage distance. A side circuit often should be added 220V voltage or above,therefore we needa creepage distance that can stand the high voltage.The usual creepage distance is 5OOV/1mm.But the distance is not enough if it is used in the high humidity environment.In this case, non-corroding resin should be printed on the surface of printed plate and so does the dampproof coating.Additionally,high voltage circuit can increase creepage distance by slotting the lines,just as follows.   (View)

IR4010 internal schematic box circuit

Published:2011/6/30 11:23:00 Author:John | Keyword: schematic box

The figure shows the IR4010 internal schematic box circuit, which indicates the internal circuit components of IR4010 device. It should be noted that it provides the VCC (voltage input response) with over or under voltage protection. When the VCC is equal to16 V, the control circuit starts to work with 6 V lag lock function. It refers that the circuit does not work with under-voltage protection when the VCC is less than (including) 10V. When the VCC is larger than 22V, the circuit does not work the either but with over-voltage protection. Comparator COMP1 controls the on-and off of the MOSFET. When the VTH (1) is larger than (including).7 V, turn off the MOSFET. Comparator COMP2 controls the connection of the MOSFET. When VTH (2) is less than (including) 1.45 V, the MOSFET is connected.   (View)
