Abstract:Macro scale synchronous electrostatic machines (SEMs) require medium voltage (5kV) and high fundamental frequencies (high pole number ~ 96) to be competitive with traditional electromagnetic machines. This paper focuses on the design, modeling, and characterization of a medium voltage current source inverter hardware platform to meet the low current and high frequency requirements of SEMs. The inverter stage utilizes JFET super cascodes for the medium voltage switches. A full-bridge front end regulates the nec… Show more
