Quality Assessment of Soft-Switching Based Single-phase Pulse Width Modulated Voltage Source Inverter (PWM VSI)

International Journal of Power Electronics and Drive Systems (IJPEDS), 2012
The authors present the design, simulation and analysis of a single phase voltage source inverter using soft switching techniques. The performance of the inverter has been compared in terms of harmonic contents present in output voltage and current. The research works for a PWM inverter along with a LLCC filter has been investigated.

Robust proportional resonant regulator for grid-connected voltage source inverter (VSI) using direct pole placement design method

IET Power Electronics, 2012
Based on the introduction of a dual-loop current control strategy for a grid-connected inverter, an averaged switching model of a grid-connected inverter with an LCL-filter in discrete domain is built under a stationary frame and a proportional resonant (PR) regulator is adopted in the current loop to track the given fundamental sinusoidal current.

Optimizing wind energy microgrids with high-speed SRG and hybrid PI controller integration

Ain Shams Engineering Journal
In this system, the wind turbine generates mechanical torque, which drives the Switched Reluctance Generator (SRG) to produce electrical power. The generated AC output is then rectified into DC, which serves as the input source for grid integration ...
