A Second Order-Second Order Generalized Integrator for Three - Phase Single – Stage Multifunctional Grid-Connected SPV System

Controller-Hardware-in-the-Loop Testing of A Single-Phase Single-Stage Transformerless Grid-Connected Photovoltaic Inverter

“…Single-phase H-bridge inverters are commonly used in PV systems due to their simplicity in design and implementation [12] [13]. To control PV inverters, different approaches, such as current controller with the grid voltage feed-forward [14], current controller with feed-forward DC-voltage regulator [15], second-order generalized integrator [16], resonant control with harmonics compensator [17], synchronous voltage control [18], are investigated.…”
