Description
The electronic circuit design like in Figure 1 above show you portable power inverter circuit using the major component called with CD4047 IC. In here we can use 12V source to charge this IC. This is IC for the monostable/astable multivibrator.
According Electroschematics blog mentioned 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.
Because the inverter has fatal mains voltages present, it is highly recommended that it be put into a metal enclosure (with adequate vent holes). The largest component is the toroidal transformer, which should be securely mounted to the chassis. A proper (TO-220) heatsink should be used with the FETs (T5-T6). Note that both the upper and lower FETs can be bolted into a single (TO220x2) heatsink plate, provided that they are insulated from each other and from the heatsink plate.
