This thesis aims to design and implement a power converter
consisting of an Ac-to-Dc converter and a Dc-to-Ac inverter for
transforming variable-voltage variable-frequency output of the studied
variable-speed permanent-magnet synchronous generator (PMSG) to a
constant-voltage constant-frequency single-phase source supplying loads.
The core controls of the proposed two power converters to switch
power semiconductor switches are by means of an IC UC3854 and a
digital signal processor (DSP) of TMS320F240, respectively. Three
single-phase power-factor-correction converters are connected to the
stator windings of the studied PMSG to control the Dc-link voltage and
correct the output power factor of the studied generator. The single-phase
inverter is properly switched to produce a constant-voltage
constant-frequency source for the connected single-phase loads.
The performance of the studied system is simulated by MATLAB
/SIMULINK and PSIM. The simulated and experimental results are also
compared to validate the characteristics of the proposed power converter
for the studied PMSG.
