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.

What is a 4th IGBT?

The fourth IGBT is a trench-gate IGBT optimized to deliver low con-duction and switching losses for high-frequency switching such as in solar inverter applications. An IGBT is basically a bipolar junction transistor (BJT) with a metal oxide semiconductor gate structure.

Which IGBT has the lowest vceon?

As can be seen in the table, a standard-speed IGBT has the lowest VCEON, 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 con-duction and switching losses for high-frequency switching such as in solar inverter applications.

When did photovoltaic inverters come out?

As early as 2013, Hopewind pioneered the distributed photovoltaic inverter solution in China, and in the following year, it realized the batch shipment of the first distributed photovoltaic inverters. From 2020 to 2022, due to the impact of the COVID-19 epidemic, the supply of IGBT modules for photovoltaic inverters were tight globally.

What is a 950v IGBT?

This new chip generation allows for compact inverters with unprecedented power density. Especially the new 950V IGBTs, in a variant for high switching frequencies as well as a variant with optimized V ce,sat, are ideally suited for use in 3-level topologies up to 1500VDC.

Can a co-pack diode be optimized for a low-side IGBT?

Co-pack diodes across the low-side IGBTs can be optimized to minimize losses during freewheeling and reverse recovery. Let’s assume a 1.5-kW solar inverter is being designed with a 230-Vac output. Which IGBT shown in the table will give the lowest power dissipation at 20 kHz?
