A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
SPWM technology can obtain low THD (1.94%) and high power factor (0.998). From the above measurement results, we verified that the single-phase inverter can obtain the best pure sinusoidal power with SPWM technology. 6. Conclusions A single-phase inverter with SPWM technology was proposed, built, and implemented.
The inverter consists of power electronics components and is based on the principles of sinusoidal pulse width modulation (SPWM) to control a full-bridge circuit and an inductor–capacitor–inductor (LCL) filter. Therefore, pure sinusoidal powers and good load regulation can be obtained from AC loads.
Generally, three sinusoidal waves are used for three phase inverter. The sinusoidal waves are called reference signal and they have 1200 phase difference with each other. The frequency of these sinusoidal waves is chosen based on the required inverter output frequency (50/60 Hz).
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
