T-shaped three-phase inverter

Is a 3 kVA active T-type NPC inverter suitable for low-voltage microgrids?

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.

What is a T-type 3-level inverter?

A T-type three-level inverter is the next step up from a standard two-level inverter. It is implemented by inserting two back-to-back switching devices between the switch node and the neutral point of the DC link created by the bulk input capacitors.

Is an active T-type inverter phase leg a standard power module?

However, with the development of new generation wide bandgap (WBG) semiconductors such as Gallium Nitride (GaN) and Silicon Carbide (SiC), and the high-performance advanced FPGA embedded microprocessors, an active T-type inverter phase leg may become a standard power module for the implementation of an idea renewable power conversion system.

What is a T-type inverter?

The T-type inverter is similar to the three-level neutral-point clamped (NPC) inverter in that it adds an additional output voltage level at 0 V, thereby offering improved harmonic performance over a standard two-level inverter.

How efficient is a three-level three-phase grid-connected inverter?

Experimental verifica-tion has been carried out based on a 3-kW three-phase T-Type NPC grid- connected inverter. FPGA based digital control technique has been developed for the current control of the three-level three-phase grid inverter. A maxi-mum efficiency of 98.49% has been achieved within a load range from 50% to 75%. 1. Introduction

What is a T-type inverter rated at 22 kVA?

The demo model shows an example of a T-type inverter rated at 22 kVA that converts an 800 V DC-bus into a three-phase 60 Hz, 480 V (line-line, rms) distribution for industrial applications. All 12 devices are configured to demonstrate the thermal loss performance of different Wolfspeed SiC MOSFETs.
