12V to 220V Inverter based MOSFET IRFZ44
Here the 12V to 220V inverter based MOSFET IRFZ44. This DC to AC inverter circuit work according to unstable multivibrator. In this inverter circuit, IC CD4047 is do the job as being a heart of unstable multivibrator, because of the fact that this IC type delivers a complementary output which has opposite phase to another (pin 10 and 11), and has 50 percent duty cycle that satisfy to generate a pulse for inverter.
To become capable of increase the current out of multivibrator so enough to generate a greater AC power as well, then we have to work with MOSFET IRFZ44. IRFZ44 delivers out high current to drive a step-up transformer, so AC power is ready at the high voltage side of transformer. This power MOSFET provides the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness.
This circuit is generally known as very simple 12V to 220V inverter because the output have not a sinusoidal signal yet, so there are many harmonic signal at the output. To reduce this signal we have to utilize a filter just like a capacitor C. As a result of this simpleness, this circuit is applicable only for lighting demand. To produce a sinusoidal DC to AC inverter, it can be possible to work with a PWM signal for driving a step-up transformer.
