Circuit diagram like in figure 1 above is Circuit Diagram Portable Power Inverter using CD4047 IC. According Electroschematics site describe that the circuit is built around the monostable/astable multivibrator CD4047 (IC1). The resistor (R2) and capacitor (C3), connected to pins 2 and 3, will decide the frequency of the astable output pulses (here, it is at about 50 Hz). IC1 gives two similar frequency outputs at pins 10 and 11 (phase of the Q and Q signals varies about 180 degrees). The square wave output signals are processed by the two-channel transistor banks (T1-T3-T5 and T2-T4-T6) to drive the power transformer (TR1). In my prototype, TR1 is a 60-VA toroidal transformer with a nominal 12-V rms secondary and 5-A current. I have powered up the inverter with an SMF battery of 12 V close to 7 Ah and successfully powered one 230-V/40-W lightbulb. The efficiency looks promising with neither the MOSFETs nor the transformer getting hotter than warm.
