Photovoltaic Inverter Simulation Model

A photovoltaic inverter is a device that converts direct current (DC) into alternating current (AC), primarily composed of a boost converter circuit and a single-phase full-bridge inverter circuit. The boost converter circuit elevates the low-voltage DC generated by photovoltaic panels to a higher voltage level suitable for the inverter circuit operation, typically implemented using PWM control algorithms with switching frequency regulation. The single-phase full-bridge inverter circuit then converts the high-voltage DC into AC power, employing techniques like sinusoidal PWM (SPWM) or space vector modulation (SVM) to generate clean AC waveforms with minimal harmonic distortion. The simulation model of the inverter enables performance evaluation of photovoltaic power stations by simulating their electrical energy output characteristics, allowing for analysis of efficiency, power quality, and grid compliance through numerical modeling of control algorithms and power electronics components.
