Analytical and calculation DC-link capacitor of a three-phase grid-tied photovoltaic inverter

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

This paper proposes a three-phase photovoltaic inverter connected to a grid with a low DC link film capacitance. Generally, photovoltaic three-phase inverters have large electrolytic DC-Link capacitors. These capacitors are known for their large size and limited operating lifetime, particularly in the case of systems with high ripple currents. This paper proposes a calculation and parameter requirements for selecting a low value film capacitor for DC-Link under high temperature conditions. The sine pulse width modulation (SPWM) was used in the oriented control system of three-phase inverters in this paper. The simulation results are presented for a 3. kW gridconnected inverter for a typical 560 V as a DC input voltage.
