A New SPWM Approach for High-Performance Single-Phase Half-Bridge Inverters with Pure Sine Wave

In order to increase the use of solar energy systems, particularly photovoltaic (PV), it is important to look beyond the direct applications of these renewable energies and focus on cost reduction measures by planning new methods of network integration. This will help increase the amount of electrical energy produced around the world. An innovative technique is to use high-frequency inverters to help filter and attenuate the current harmonics supplied to the output of the filter. This is an innovative technique for producing fast complementary digital PWM signals with dead time to control a single-phase half-bridge inverter. To implement this technique, the study recommends using the IR2110 controller, a device widely used for switching control of MOSFETs. This circuit was created and is controlled by a high-frequency PWM signal generated by a microcontroller driver board using a specified program. The application of this solution can be applied to different renewable energy conversion systems. The results of the experiments show that this embodiment is effective. Future research directions could include exploring advanced modulation techniques, improving system performance and efficiency, analyzing the impact of PWM on system stability and harmonics, and integrating PWM techniques with emerging power electronics technologies.
