These inverters not only increase the efficiency of the power system but also prevent electrical components from damaging. Much work has been done in the field of pure sine wave inverter but for a waveform with low number of harmonics along with high efficiency is still an open challenge.
The paper concentrates on the use of renewable solar energy by incorporating a multi-vibrator IC (NE-555), in this case operating in a stable mode, the PWM generating technique used to drive a pure sine wave inverter. It appears that the design is easy to implement and proves to be cost-effective for low power applications . II.
In this paper, a multi-vibration technique is used to generate a square wave which is then split into two square waves of the same frequency by the 4017-decade counter to hold the H-bridge inverter. The output of the H-bridge inverter contains harmonics that are filtered using a low pass filter. Thus, we get a pure sin wave in the output.
The Modified Square Wave also known as the Modified Sine Wave Inverter produces square waves with some dead spots between positive and negative half-cycles at the output. The cleanest utility supply like power source is provided by Pure Sine Wave inverters.
Abstract— Pure sine wave transformers are very important nowadays when it comes to using ds power sources for both low and high-power applications. These inverters not only increase the efficiency of the power system but also prevent electrical components from damaging.
Also, a low pass filter design is tested to convert a distorted square wave to a pure sine wave with minimal ripples on any load condition. The results shown are simulated based, indicating the correct form of output with 220V AS with very less harmonics storms and noise effects.
