Simple DC to AC Inverter using CD4047

This circuit is DC to AC inverter, where the circuit does not work based on the stable multi-vibrator does. On this circuit using CD4047 IC as the heart of multi-vibrator is not stable, because this type of IC to provide a complementary output stage, contrary to the other (pins 10 and 11, as shown in Figure 1), and 50% of the cycle to meet the obligation to produce pulse inverter.

Circuit is called a simple DC to AC inverter, as there is no output signal is not sinusoidal, and there were lots of harmonic signals on the output. To suppress this signal we have to use a filter such as capacitor C. Because of this simplicity is only suitable circuits for lighting needs. To build a sinusoidal inverter DC to AC. At the circuit this multivibrator is used to make power is too high, then we have to use the MOSFET IRFZ44. IRFZ44 provide high current to drive step-up transformer, so power is available in addition to the high voltage transformer.
