6 FAQs about [Does photovoltaic inverter need IGBT ]

What is the role of IGBT in an inverter?

As a power device, IGBT (insulated gate bipolar transistor) plays the role of power conversion and energy transmission in the inverter, and is the heart of the inverter. At the same time, IGBT is one of the most unreliable components in the inverter, which is very sensitive to the temperature and current of the device.

How many IGBTs does a solar power inverter use?

Based on these fundamental benefits, this power inverter uses IGBTs as the power switches of choice. Because the topology employed for the power inverter is fullbridge, this solar inverter design uses four high-voltage IGBTs (Fig. 1). While transistors Q1 and Q2 are designated as high-side IGBTs, Q3 and Q4 are labeled as low-side power devices.

Which IGBT is best for a low power inverter?

Examining a variety of switching techniques and IGBT blends, the best combination for attaining the lowest power losses and highest inverter performance is to use ultrafast trench IGBTs for high-side transistors and standard-speed planar devices for the low-side section (Fig. 2).

Are insulated-gate bipolar transistors a good choice for solar inverter applications?

For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) ofer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.

Can IGBT degradation cause a failure of an inverter?

This IGBT degradation would most likely not cause the failure of an inverter, but could degrade performance. Furthermore, it is highly questionable if a device exhibiting significant instability would operate for the expected lifetime of an inverter (i.e. 5 to 20 years).

Which EF-ficiency is possible for a solar inverter design?

The latest 600-V trench IGBT is optimized for switch-ing at 20 kHz. It can be seen that this IGBT has lower total power dissipation compared to the previous-generation planar IGBT (Fig. 4). We can conclude that the highest ef-ficiency possible for a solar inverter design, a trench-gate
