Voltage source inverters (VSI) and current source inverters (CSI) are two types of inverters used in power electronics to convert DC (direct current) to AC (alternating current). They have distinct characteristics and applications, making them suitable for different use cases. Let’s dive into the details of each type.
In a CSI, the current source input implies that when an open circuit fault occurs, the inverter cannot inherently limit or control the output voltage. This limitation can result in overvoltage conditions, posing risks to connected equipment and the grid. Additionally, it can lead to reduced system efficiency and compromised power quality. 5.
