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.
So the THD of the novel T-type inverter is the lowest. From Figure 14 we see that the common mode current of the proposed novel T-type inverter is smaller than the previous T-type inverter topology. In conclusion the proposed hybrid T-type inverter has priority compared to the NPC and T-type inverter.
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.
The current and voltage THD comparison of three types of inverters. The topology and control strategy of the two circuits are the same, except the devices used. The T-type topology consists of 12 IGBTs, while the hybrid T-type topology consists of 9 MOSFETs and 3 IGBTs.
2. T-Type NPC Inverter The 3-level active T-type NPC inverter, as show in Figure 1(b), provides an ad-ditional middle point of its DC-link voltage for its voltage switching, and thus the inverter voltage is reduced to half compared with the conventional 2-level inverter as shown in Figure 1(a).
