standard-speed IGBT has the lowest conduction loss, but its highest switching loss makes the device unsuitable for the high-side IGBTs. 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).
Contemporary solar applications require very highly efficient, power-dense and lightweight grid-tied inverters. Traditionally, IGBT has been the device of choice in both three-phase and single-phase (≤10 kW) solar inverter designs while superjunction (SJ) MOSFETs (600/650 V) also have been used in some single-phase designs.
Designing custom motor and inverter power electronics using discrete IGBTs to fit specific requirements can be costly in the long term and delay design schedules. Instead, designers can use off-the-shelf IGBT modules which combine multiple power devices into a single package.
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.
As the photovoltaic (PV) industry continues to evolve, advancements in Is the photovoltaic inverter IGBT a power board have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Is the photovoltaic inverter IGBT a power board ]
Can IGBTs be used in a solar inverter?
These topologies use IGBTs as the power discrete semiconductor of choice for achieving high eficiency and high reliability. This application note presents how Bourns® Trench-Gate Field-Stop (TGFS) IGBTs with co-packaged Fast Recovery Diodes (FRDs) can be used in a solar inverter application to enable eficient power conversion.
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.
Can Bourns® Trench-Gate field-stop (TGFs) IGBTs be used in a solar inverter?
This application note presents how Bourns® Trench-Gate Field-Stop (TGFS) IGBTs with co-packaged Fast Recovery Diodes (FRDs) can be used in a solar inverter application to enable eficient power conversion. It also outlines the optimal IGBT features necessary for superior thermal performance while delivering low power dissipation.
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.
How do IGBTs work in a PV inverter?
During operation inside a PV inverter, IGBTs are subject to AC stress conditions as opposed to DC stress conditions. This typically consists of a 60 Hz on-off cycle, with a Pulse-Width-Modulated (PWM) signal on the order of 10 – 15 kHz superimposed on the lower-frequency cycle.
