Design & Implementation of Single Phase Pure Sine Wave Inverter Using Multivibrator IC

Pure sine wave inverters are demand of modern era whenever it comes to utilization of DC power sources for both low and high power applications. These invertors not only increase the efficiency of the power system but also prevent the electrical components from damaging. Research has been carried out on producing cost-effective and efficient pure sine wave inverter in recent times and this paper proposes a design that is highly useful for low power based applications. Paper focuses on utilizing renewable solar energy by incorporating Multi vibrator IC (NE 555), in this case operating in A-stable mode, for the PWM generation technique used to drive pure sine wave inverter. It is shown that the design is easy to implement and proves to be cost effective for low power applications.
