A variable-speed constant frequency (VSCF) power conversion scheme with a permanent magnet synchronous generator (PMSG) is studied in this dissertation. The scheme consists of a PMSG, diode-rectifier bridge, dc-link filter, controlled converter for conversion to the constant frequency ac utility, and transformer. The various subsystems listed above are modeled for steady-state analysis and the simulation results are experimentally verified. All the relevant performance equations are derived for both the three-phase half-wave (THWI!) and full-wave (TFWI) controlled converter options and the harmonics are computed.
