Design of reduced switch count multi-level inverter based electric spring for critical load voltage stability

This paper presents Transistor Clamped H-Bridge (TCHB) inverter-based Electric Spring (ES), a demand side management device that enhances the voltage stability of the critical load connected to the grid through Renewable Energy Sources (RES). This configuration of ES provides the solution to voltage sag/swell for reduced size, %THD and input power required. To validate the effectiveness of the system performance of TCHB-based ES, detailed simulation studies are performed using MATLAB/Simulink environment.
