Technical FAQs 4

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 much power does a three-level T-type inverter lose?

For a three-level T-type inverter with a power rating of 11 kVA, we selected SiC devices with an RDS(on) of 75 mΩ and a blocking voltage of 1.2 kV for Q1 and Q2, and 60 mΩ and 650 V for Q3 and Q4 (see Figure 40). With a switching frequency of 100 kHz, we measured an average total loss of 130 W in the active components from the 12 switches.

What is the eficiency of a T-type inverter?

Figure 74. Eficiency results when having the 10-kW, Bidirectional Three-Phase Three-Level (T-Type) Inverter and PFC Reference Design operating as a T-type, 2-level and Vienna rectifier. For all power ratings, we achieved an eficiency higher than 98%.

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.
