Summary:A single-stage three-phase voltage source inverter for high-voltage PV modules is presented. The benefits of the proposed design are simplicity, low cost, high efficiency, and high reliability. The inverter is intended for module integration and is designed for a relatively low power rating of approximately 250W. Analytical models and dynamic simulation are used to calculate expected efficiency. The mean time to failure is estimated using established methods. Component costs are approximated with a linear regression which relates device ratings with price data. It is shown that in comparison to conventional single-phase module-integrated converters, the power component cost reduction is approximately 60%, peak efficiency is increased above 98%, and longer life is anticipated. Experimental results are shown.
