Mosquito Swatter
It is an electronic device that produces high voltage around 300-400 volts in the nets. When the mosquito passes through the outer and inner nets of the swatter, its wings short out and sparks which will destroy it.  The mosquito swatter circuit consists of three sections.
1.      AC to DC converter
AC is directly step-down using the AC capacitor and rectified through full wave Diode Bridge. A low value smoothing capacitor is also present. This DC is used for charging the battery in rechargeable types.  But in non rechargeable types, AC-DC conversion is not present.
2.      Oscillator
A transistor based oscillator is present to generate pulses. The transistor switches on and off rapidly to create a rising and falling voltage for the transformer to step up.
3.      A step-up transformer to generate high voltage AC by inverting the DC to AC.
4.     Net or Grid – The high voltage low current pulses passes into the net. The grid set up has three nets. Two outer nets are negative and the middle one is positive.

When the mosquito swatter is switched on, and gently swings, the electric field from the net attracts the mosquitoes and they try to move though the net which gives a fatal shock.

Dear sirs,

              Read simple details given about a mosquito killer (bat)of electronic nature with rechargable battery)Since the circuit diagram is not given with drawing&actual parts  I could not find out the actual values(techenical values like microfarads,resistance values like  ohms   etc   of the components. as I want to make one simple Mosquito Bat with u r techenical advice plz send me by my email th circuit draing with actual components by return post to test the working of it.Plz send by emal:   (  chandran.ariyandath@gmail.com   ).  Thanks.Chandran(Retd Engr)29512

Sirs,

 

        i also ask for the actual values of mosquito killer (techenical values like microfarads,resistance values like  ohms   etc   of the components. as I want to make one simple Mosquito killer in my house. Please send me the values by email drinalds@yahoo.com, drinalds777@yahoo.com. thanks..

Sir   I want to kow the exact
