This thesis report will explore current source inverter (CSI) design through simulations, hardware design and hardware testing. With development of wide bandgap devices and increasing commercial availabilities, higher switching frequency is achievable with manageable losses. Many benefits derive from higher switching frequency, such as passive component size reduction by reducing energy storage requirement, greater integration, and faster transient response. However, many problems also arise with higher switching frequency using modern voltage source inverter, such as greater dv/dt at the output terminal and higher common mode electromagnetic interference. Because of VSI limitations at higher switching frequency, CSI will be explored to see whether this old topology can provide new solutions. There are few key benefits of CSI such as low output voltage dv/dt, boosting characteristics, and limited shot through state, which will be presented in this report.
