Inverter 100W by IC 4047 + 2N3055 with PCB

This circuit power Inverter 100W, so input voltage 12V (battery 12V)
to output volt 220V ac 50HZ, it is asy circuit because less component to use.
It use IC CD4047 Squarewave Oscillator 50HZ and
Power Transistor 2N3055 x 2 For driver transformer 220V ac to OUTPUT Power 100W min.

  1. whats the current specification of 12-0-12 volt transformer?

    which terminal of cx is connected to the VR1,?

    and which terminal of c1 is connected to ground?

    please reply

  2. nice meeting professionals,pls i nd automatic lead battery charger circuit. D type dt tn off once d battery attain fully charged says:

    please post auto-lead acid battery charger

  3. i,m trying 2make a macro for IC:CD4047 and transistor 2N3055, i need the internal circuits or the logic diagrams for this components…
    thank you,
    plz rply as soon as possible..

  4. can you give the information about. mosfet gate voltage how voltage. means that if very the gate voltage then the power out put voltage low or high?

  5. Hi,
    Please explain-
    D1 = ?
    ZD1 =?
    CX =?
    Resistor wattage
    Ampere of transformer and Ah of battery up to we use.

  6. D1 = may be means cd4047 ic but where is D1
    ZD1 =zener diod 9volt 0.5watt
    CX =o.o1/0.022 Ceramic
    capacitors..
    transformer Amp will be 2-3 amp..
    batter will around 12 volt 5-10 amp..
    rasistance will be quater to half watt…

  7. Please sir, there is no mosfet on the circuit, can it work perfectly without using mosfet ? Hoping to hear from u. Thanks

  8. 1) 100 watts output requires 8 amperes of transformer.
    2) The resistor and zener in series from main 12vdc battery source is just voltage regulation to steady 9vdc. you may omit this since CD4047 can operate 15vdc max.
    3) D1 is circuit protection from battery polarity reversed connected which will blow the fuse.
    4) To calculate the output frequency, adjust values of VR1 and for other higher frequencies change CX value. Frequency=1/(4.4(R)(C))

  9. CD4047 as well as the ever reliable 555 timer astable mode is very useful in creating isolated output power supplies, though a lot of single chip DC-DC converter IC available to do the isolation.
