Abstract
:1. Introduction
- Giving mathematical expressions that present the parameters that affect the SH emissions of GCIs;
- Studying the effect of some of the parameters on the emissions of GCIs mathematically by simulation and by experimental studies;
- Studying the effect of parameters’ symmetry and asymmetry of parallel-connected GCIs on the total emissions to the grid;
- Giving a corner stone for studying the propagations and penetration of SH emissions of GCIs in single-phase installations in addition to filtering them out and preventing them from flowing into the grid.

5.1. GCI Model
5.2. Simulation with One GCI
- The amplitude of the SH emissions of single-phase GCIs depends on the DC-link voltage and the coupling filter inductance.
- The relationship between the DC-link voltage and SH emissions amplitudes of GCIs is non-linear.
- The amplitudes of the SH emissions of GCIs are in an inverse relationship with the coupling filter inductance.
- The amplitude of the SH emissions of single-phase GCIs are independent of the active power variation.
- The phase of the carrier harmonics is independent of the active power variations
- The active power variation affects only the phase of the sideband harmonics.
