POWER ELECTRONICS AND RENEWABLE ENERGY SYSTEMS: INNOVATIONS IN SUSTAINABLE ENERGY CONVERSION TECHNOLOGIES

Abstract

The increasing demand for sustainable energy solutions accelerated the adoption of renewable energy systems and advanced power electronics technologies. This study examined the role of power electronics in renewable energy systems and investigated recent innovations in sustainable energy conversion technologies. The research focused on evaluating the influence of power electronics innovation, advanced semiconductor technologies, smart grid integration, and intelligent energy management on sustainable energy conversion performance. A quantitative research design was employed, and data were collected from a sample of 300 professionals working in renewable energy organizations, power utilities, engineering firms, and research institutions. Data analysis was conducted using descriptive statistics, reliability analysis, correlation analysis, and multiple regression analysis. The findings revealed strong positive perceptions regarding all study variables, with mean scores ranging from 4.18 to 4.37. Reliability analysis produced Cronbach’s alpha values between 0.84 and 0.89, indicating strong internal consistency. Correlation results demonstrated significant positive relationships among all variables, with coefficients ranging from 0.723 to 0.846. Regression analysis showed that intelligent energy management exerted the strongest influence on sustainable energy conversion performance (β = 0.351, p < 0.001), followed by power electronics innovation (β = 0.318, p < 0.001). The model explained 77.8% of the variance in sustainable energy conversion performance (R² = 0.778). The study concluded that technological innovations in power electronics significantly enhanced renewable energy integration, energy efficiency, system reliability, and sustainable energy development, supporting the global transition toward low-carbon and resilient energy infrastructures.
