A Single-Stage Z-source Inverter for Transformerless Grid Connection with a Proportional-Resonant Controller for DC Current Elimination
2020
2020 IEEE 11th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)
The ever-rising number of grid-connected inverters contributes to an increase of DC current injection into utility grid, resulting in the saturation of distribution transformers, metering errors and the corrosion of earthling conductors. A transformerless single-stage Z-source inverter uses only two switching devices in its converter circuit to generate sinusoidal voltage as that of a full-bridge inverter. However, this inverter has the problem of having a DC offset in the AC waveform due to
