Three-phase currents of each inverter are controlled independently, which is easy to be realised by a microcontroller. In order to verify the effectiveness of the current control strategy, the grid-connected experiment of a single three-level T-type inverter is carried out at first.
In recent years, compared with the neutral-point clamped (NPC) inverters, the three-level T-type inverters (3LT2Is) are widely used in the photovoltaic grid-connected power generation systems and other AC/DC interfaces due to their advantages of fewer power devices, less switching losses and higher efficiency [1, 2].
Abstract: Multiple parallel three-level T-type inverters (3LT2Is) have become the trend in large-power low-voltage applications. In parallel operation of modular 3LT2Is, three aspects including current sharing control, circulating current suppression and neutral-point potential (NPP) balance control should be considered.
Y.-Y. (2017) Design and Implementation of a Three-Phase Active T-Type NPC Inverter for Low-Voltage Microgrids. Energy and Power Engineering, 9, 70-77. This paper presents the design and implementation of a 3 kVA three-phase active T-type neutral-point clamped (NPC) inverter with GaN power devices for low-voltage microgrids.
Experimental verifica-tion has been carried out based on a 3-kW three-phase T-Type NPC grid- connected inverter.
