Podgorica high frequency sine wave inverter

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.

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.

When it comes to powering electronic devices and appliances, a pure sine wave inverter holds an advantage over a modified sine wave inverter by producing a cleaner and more stable waveform. This is particularly crucial for appliances that require a high-quality power source.

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.

To produce a sine wave output, high-frequency inverters are used. These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time. For example, very narrow (short) pulses simulate a low voltage situation, and wide (long pulses) simulate high voltage.

The simulation results show that output of H-Bridge inverter (Channel C) is being filtered to an extent where pure sinusoid waveform is obtained (Channel D). Same has been observed in practical realization of inverter, that is, the waveform at the output of H-Bridge is not pure sinusoidal in-fact a triangular wave is obtained from bridge output.
