Abstract
This paper demonstrates that by modifying the basic period of the
conventional repetitive controller in synchronous reference frame a number of
benefits can be achieved. Among these benefits are: (i) a simple solution for
the saturation of the output transformer due to the pole-zero cancellation
issue; (ii) an additional degree of freedom for the selection of the harmonics
to be rejected in abc stationary
frame; (iii) a reduction of the memory space requirement for the implementation;
(iv) an increase of the stability margin. As a result it is possible to obtain
output voltages with reduced total harmonic distortion (THD) for both linear
and non-linear loads. In order to confirm the claimed advantages of the
proposed repetitive controller in synchronous reference frame and to demonstrate
the steady-state performance, experimental results from a 10kVA space vector
modulated three-phase inverter, fully controlled by a DSP TMS320F241, are
presented.
