“…This proposed design implements this filter using the information about the resonance frequency. Very promising research related to the design considerations of L-C filters for sine-wave inverters has been performed by [6] [10]. When an L-C filter is used to filter out the sine-wave from the modified PWM waveform, harmonics with resonant frequency of L-C circuit are also added up in the output.…”

“…When an L-C filter is used to filter out the sine-wave from the modified PWM waveform, harmonics with resonant frequency of L-C circuit are also added up in the output. Hence a suitable and economical approach lies in to use such values for inductance and capacitance that give at least ten times higher resonance frequency than the cut off frequency of the filter [6]. Resonance frequency or natural frequency of an L-C filter is given in (1).…”

“…An economical design of a 220V/50Hz with sine-wave output has been presented in [2]. This proposed design improves the approaches adapted in [1] [3][4] [6] by further simplifying the system realization and providing dual output. Proposed design could be used as an integral part of uninterruptable power supplies (UPS), grid of photovoltaic solar panels, wind turbine or the lead-acid batteries.…”

A novel, improved and economical approach for a universal voltage source sine-wave inverter is presented in this paper. Existing inverters methodologies with sine-wave output are expensive and sometime go beyond the budget for home application. Common drawbacks associated with existing low cost inverters are square-wave output, bulky size, noisy output voltage and poor efficiency. In addition to that, low cost inverters provide output only with one power distribution standard i.e. 110V/60Hz or 220V/50Hz. Proposed design of a low cost sinewave inverter facilitates user to select any voltage standard of these two using a single physical unit. This brings novelty and universality in this proposed design. Proposed approach makes use of a microcontroller unit (MCU) to generate the pulse-width modulation (PWM) sine-wave in contrast to the conventional sine/triangular PWM approach. The low-cost implementation, least harmonic sine-wave output, availability of two output power standards, and auto-shutdown protection against overloading make proposed methodology an ultimate choice for use in homes and offices as a supplementary way of power.Index Terms -PWM sine-wave, Full wave bridge, Voltage source inverter, Lowpass filter, Microcontroller, Total harmonic distortion, Centre-tapped transformer.

“…Supplies (UPSs) are quasi-sine wave inverters or square wave inverters. If an electronic device operated by these inverters, it will be damaged because of the contents of the harmonics [6,7]. The generation of a pure wave is significance in 661 electronics energy but, the majority of the existing sinusoidal wave inverters are costly and the production is straight.…”

This paper offers a two-stage boost converter for a single-phase inverter without transformer for PV systems. Each stage of the converter is separately controlled by a pulse width modulated signal. A Simulink model of the converter using efficient voltage control topology is developed. The proposed circuit performance characteristics are explained and the obtained simulation results are confirmed through the applied experiments. Moreover, this paper has examined the control circuit of a single-phase inverter that delivers a pure sine wave with an output voltage that has the identical value and frequency as a grid voltage. A microcontroller supported an innovative technology is utilized to come up with a sine wave with fewer harmonics, much less price and an easier outline. A sinusoidal pulse width modulation (SPWM) technique is used by a microcontroller. The developed inverter integrated with the twostage boost converter has improved the output waveform quality and controlled the dead time as it decreased to 63 µs compared to 180 µs in conventional methods. The system design is reproduced in Proteus and PSIM Software to analyze its operation principle that is confirmed practically.

This paper gives comparative analysis between Synchronous Pulse Width Modulation (SPWM) and square wave output filtration based pure sine wave inverter. The paper also explains the detailed working of square wave output filtration based pure sine wave inverter. The SPWM based technique uses varying pulse at gate of power devices which can be generated through microcontroller according to requirement of output. The square wave output filtration based technique uses simple pulse which can be generated from multi-vibrator and output is filtered using Chebyshev's low pass filter to generate pure sine wave. The results of both types of techniques are tested using Simulink.
