Common-Ground Transformerless Grid-Connected Inverters

2020
Rule 1 for eliminating leakage current of full-bridge TLIs and Rule 2 for eliminating leakage current of half-bridge TLIs have been discussed in Chaps. 3 and 4, respectively. This chapter focuses on Rule 3 used in common-ground TLIs. Common-ground TLIs mean that the neutral line of the grid is directly connected to the negative terminal of the PV ...

A Model Predictive Control Method For Common Grounded Photovoltaic Multilevel Inverter

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
Leakage currents represent critical issues for the operation of conventional photovoltaic (PV) inverter topologies. Recently, the common grounded (CG) PV inverter topologies have presented superior performance over the conventional PV inverter topologies from the leakage currents elimination point of view.

Step-Up Seven-Level Common-Ground Transformerless Inverter

2021 14th IEEE International Conference on Industry Applications (INDUSCON), 2021
This paper proposes a new multilevel inverter for single-phase transformerless systems. The main feature of the proposed topology is to synthesize seven output voltage levels with high voltage gain. In this topology the ground connection is shared between the dc input and ac output which results in constant common-mode voltage, therefore theoretically ...

Five-level Common Ground Type Inverter for PV Application

2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2020
In renewable energy sources transformer-less grid-tied inverters are widely used due to their higher efficiency, reduced cost and size. With the absence of transformer, there exists leakage current due to PV-to-ground parasitic capacitance leads to deteriorated power quality, cause personal safety issues and electromagnetic interference (EMI).

A Single-Phase Common Ground Boost Inverter for Photovoltaic Applications

2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018
The paper introduces a new single-phase boost inverter for photovoltaic applications. The introduced inverter merges a boost converter and a single-phase inverter in a single-phase single-stage inverter. The proposed inverter has a simpler topology and uses the minimum number of power electronic components.

A Dual-Boost H -Bridge Inverter With Common Ground for Photovoltaic Interfacing

IEEE Transactions on Industrial Electronics, 2021
Microinverters for photovoltaic (PV) energy conversion typically encounter challenges, including the requirement of a voltage boost and suppression of the high-frequency leakage current. These challenges are usually not met simultaneously if only a standard full ( H )-bridge is used.

Common-Ground-Type Transformerless Inverters for Single-Phase Solar Photovoltaic Systems

IEEE Transactions on Industrial Electronics, 2018
This paper proposes a family of novel flying capacitor transformerless inverters for single-phase photovoltaic (PV) systems. Each of the new topologies proposed is based on a flying capacitor principle and requires only four power switches and/or diodes, one capacitor, and a small filter at the output stage.
