FAQ: What are current source inverters and voltage source

Sep 16, 2016 A key difference between CSI drives and VSI drives is their energy storage method. CSI drives use inductive energy storage—that is, they use inductors in their DC link to store DC energy and regulate current ripple between the converter and the inverter. Conversely, VSI drives use capacitive storage, with capacitors in their DC link, which

Current Source Inverter : Circuit Diagram and Its Advantages

The inverters are used to convert the power from dc to ac. The voltage source inverter (VSI) and current source inverter (CSI) are two types of inverters, the main difference between voltage source inverter and current source inverter is that the output voltage is constant in VSI and the input current is constant in CSI. The CSI is a constant current source which supplies ac to the input, and
