San Jose Solar Inverter IGBT Module

Why is IGBT used in inverter applications?

Understanding why IGBT is used in inverter applications helps in proper implementation: High Voltage Handling – Supports hundreds to thousands of volts. Fast Switching – Reduces power loss in high-frequency circuits. Efficiency – Lower heat generation compared to older transistors. Reliability – Robust under heavy loads when used correctly.

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.

Why are IGBT and Diode Modules made thinner and miniaturized?

The IGBT and diode devices that constitute these modules have been made thinner and miniaturized to optimize the device structure. This has reduced the power loss during inverter operation compared with the conventional products (Fuji Electric's 6th-generation V Series)

How do you test an IGBT inverter?

Before finalizing your IGBT inverter, test thoroughly: Check Switching Waveforms – Use an oscilloscope to verify clean transitions. Measure Power Losses – High losses mean poor efficiency. Inspect for Overheating – Hot spots indicate bad thermal design. Learning how to use IGBT in inverter systems correctly ensures reliability and efficiency.
