Compared with the voltage source inverter, the current source inverter has the boosting characteristics, and the AC side does not need a complex and bulky filter unit, but it also has the problem of current control of the DC energy storage inductor.
The rapid growth of PV systems as a clean and systems is the current source inverter (CSI). CSIs offer several advantages over other PV installations. Interconnected systems are categorized according to the quantity of power PDF | Grid converters play a central role in renewable energy conversion.
At present, most electrochemical energy storage systems in the grid use a single-stage PCS with nominal DC-link voltage less than 1,000 V. At this scale, charge imbalances and reliability issues in the storage system are manageable, and simple voltage source inverter (VSI) topologies offer satisfactory performance.
Voltage source inverter (VSI) has the advantages of simple structure and flexible control, and is widely used in electric energy conversion occasions such as motor drive and new energy power generation [ 1 ].
