Three-Phase PV Inverter Current Loop with PI Control Simulation in Simulink

Resource Overview

Simulink simulation of three-phase photovoltaic inverter current loop control using PI (Proportional-Integral) controllers for performance analysis and system validation

Detailed Documentation

This Simulink simulation implements current loop control with PI controllers for a three-phase photovoltaic inverter to model and analyze its operational performance. The simulation typically includes Park/Clarke transformations for dq-frame current control, PI regulator tuning for zero steady-state error, PWM generation algorithms, and inverter switching logic. Key components involve current sensors, reference tracking mechanisms, and stability analysis tools to evaluate dynamic response under various load conditions.
