Figure 8 shows phase waveforms of input voltages [u.sub.S1], [u.sub.S2], [u.sub.S3] with single-phase rectifier deformation in the second phase.
Channel 1--compensating voltage generated by the filter [u.sub.c1], channel 3--output voltage filtered by SAPF [u.sub.L1], channel 2--voltage distorted by a single-phase rectifier [u.sub.S1].
Three-phase waveforms of input voltages, channel 1--power network voltage [u.sub.S1], channel 2--voltage distorted by a single-phase rectifier [u.sub.S2], channel 3--power network voltage [u.sub.S3].
Figure 1 shows a typical single-phase rectifier
circuit, with power factor correction capability.
Improvement of input current waveforms of a single-phase rectifier
 has only considered the absorbed active power of a single-phase rectifier with constant power load instead of state-space model.
In this paper some significant contributions can be distinguished comparing with similar and preliminary works which have studied only single-phase rectifier. First contribution is considering three-phase form of rectifiers since it is dominating structure in high and medium powerapplications.
A growing number of current waveshaping methods applied to single-phase rectifier are now available including active and passive methods and selection of the best-suited method for a particular case can be a complicated decision making process, .
The object of this paper is to propose and analyze a novel single-phase rectifier (Figure 4).
