Development and Implementation of Smart Inverter System for Future Power Demand Through Renewable Source

Abstract

A sine wave is a smooth, continuous oscillation representing the ideal form of AC power, characterized by a single frequency (e.g., 50/60 Hz) and minimal harmonic distortion, ensuring compatibility with all electrical devices and the utility grid. The normal wave (commonly referring to a Modified Square Wave or Quasi-Sine Wave) is a stepped, non-sinusoidal waveform composed of a fundamental frequency and significant higher-order harmonics. The Pure Sine Wave inverter achieved an estimated efficiency of 85-90%, whereas the Square Wave inverter stayed around 35 39%.Charging of Sine Wave system reached 14.02V (3% higher than Square Wave).Discharge of Sine Wave system was 30% more resilient at the end of the test period (7.90V vs 6.06V). The OLED display confirmed a 50Hz stable frequency. This analysis confirms that the Pure Sine Wave Inverter is the most viable solution for future power demands through renewable sources due to its efficiency and compatibility with modern household appliances.
