Using a standard multimeter, IGBT modules can be tested quickly to verify the following three things: The relative emitters are shielded from the Gate terminals; the Diodes are looking great; The IGBTs are in great shape.
The IGBT is capable of handling extremely high voltage and power. The MOSFET can only handle low to medium voltages and power.
IGBT can only be used for frequencies below a few kilohertz. MOSFET can be utilised for extremely high recurrence (of the request for MHz) applications.
An IGBT’s most fundamental function is to switch electric currents as quickly as possible while minimising switching losses.
An IGBT is a bipolar transistor with an isolated gate structure, as indicated by its name, “Insulated Gate Bipolar Transistor.
” The gate itself is essentially a MOSFET. In 400- to 1250-V applications, IGBTs and MOSFETs are used for different things: IGBTs are used in inverter applications that require high overload endurance and a switching frequency of less than 20 kHz.
Inverter applications with a switching frequency greater than 20 kHz call for MOSFETs.
The Global IGBT and MOSFET Test System market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Teradyne, Inc. The ETS-88TH, the most recent addition to the ETS-88 product line for testing power module, IGBT, and MOSFET devices, is now available from TER).
With the ability to combine AC and DC testing in a single device insertion, the ETS-88TH offers lower overall test costs.Features of the ETS-88TH include:
New instruments for testing dynamic switching, such as the AC-2500 Option, include waveform capture for AC parameters like TDon/off, Trise/fall, Eon/off, Trr, Qrr, UIL, and Qg.
Signal path with low inductance that allows for testing at greater power levels and switching speeds to improve device performance specifications.
Based on our testing, Multi-Sector Technology increases throughput by delivering 99 percent test efficiency for parallel applications and a 50 percent reduction in test time for index parallel applications.
With its powerful software tools for rapid device characterization and production development, EagleVision MST Software accelerates time to market.
According to the Business Development Manager for Teradyne’s Consumer Power Business Unit, “The ETS-88TH has proven superior AC test performance for discrete and power module devices while lowering the cost of test for customers.
Customers benefit from the AC-2500 instruments’ low inductance path, fast waveform transfer, and increased device specifications, test coverage, and throughput.
