Tóm tắt

The rapid deployment of renewable energy technologies has significantly accelerated the adoption of solar photovoltaic systems in modern power networks. In this study, a hybrid multilevel inverter (HMI) architecture, consisting of a three-leg voltage source inverter combined with H-bridge modules and an output LC filter, is proposed for standalone photovoltaic applications. The system is capable of supplying balanced and unbalanced nonlinear AC loads while maintaining voltage quality. A multi-carrier PWM strategy together with a proportional–integral voltage controller is implemented to regulate the output voltage. The operational performance of the proposed inverter is verified through detailed PSIM-based simulations.
