6 FAQs about Basis for choosing IGBT for solar inverter

What is IGBT in solar inverter?

In solar inverter applications, IGBTs (Insulated-Gate Bipolar Transistors) offer benefits compared to other types of power devices, such as high-current-carrying capability, gate control using voltage instead of current, and the ability to match the co-pack diode with the IGBT.

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) offer 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.

What are the different inverter types for IGBTs?

What is a solar inverter?

A solar inverter is a power-electronic circuit that converts dc voltage from a solar array panel to ac voltage that can be used to power ac loads such as home appliances, lighting and power tools. However, getting the most out of such a topology requires careful analysis and the right choice of the high-side and low-side combination of an IGBT.

Which IGBT has the lowest V CEON?

As can be seen in the table, a standard-speed IGBT has the lowest V CEON, but the slowest fall time compared to the other two fast and ultrafast planar IGBTs. The fourth IGBT is a trench-gate IGBT optimized to deliver low conduction and switching losses for high-frequency switching such as in solar inverter applications.

How many switches are used in a solar inverter?

A typical implementation of a solar inverter employs a full-bridge topology using four switches (Fig. 2). Here, Q1 and Q3 are designated as high-side IGBTs while Q2 and Q4 are designated as low-side IGBTs.
