Solar inverter current ripple principle

These ripples are produced by the chopping effect of inverter switches, causing the DC-link current to fluctuate around the required average current, consequently requiring a large DC-link capacitor. In a single-phase photovoltaic power generation system, a 120 Hz ripple voltage occurs in the DC-link capacitor due to the use of a full-bridge inverter. By. Almost any solar systems of any scale include an inverter of some type to allow the power to be used on site for AC-powered appliances or on the grid. Different types of inverters are shown in Figure 11. The interleaved superposition of the DC link currents in these systems can potentially be adjusted.
