The igbt, which combines the advantages of gtr and mosfet, is a new type of insulated gate bipolar transistor that was introduced in the 1980s. It has convenient control, high operating frequency, fast switching speed and large safe working area. With the continuous improvement of voltage and current levels, igbt has become an ideal power switching […]
IGBT (Insulated Gate Bipolar Transistor) is a minority carrier device with high input impedance and strong current carrying capacity. From the circuit designer’s point of view, IGBT has input characteristics of MOS devices. And the current output capability of the bipolar device is a voltage-controlled bipolar device. The purpose of the invention of the IGBT is […]
As one of the important high-power mainstream devices for power electronics, IGBT has been widely used in household appliances, transportation, power engineering, renewable energy and smart grid. In industrial applications such as traffic control, power conversion, industrial motors, uninterruptible power supplies, wind and solar equipment, and frequency converters for automatic control. The IGBT module is a modular semiconductor product […]
IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has MOSFET The advantages of both the high input impedance and the low turn-on voltage drop of the GTR. The GTR saturation voltage is reduced, […]
The drive circuit of the IGBT must have two functions: one is to achieve electrical isolation between the control circuit and the gate of the driven IGBT; the other is to provide a suitable gate drive pulse. There are many driving circuits for IGBTs, and the driving circuit for discrete components is simple and inexpensive. The dedicated […]
First, what is IGBT?

The GTR saturation voltage […]
Igbt module inverter circuit diagram design (1)The essence of solar photovoltaic power generation is that under the illumination of sunlight, the solar array (ie, the PV module square array) converts the solar energy into electrical energy, and the output direct current is converted into the alternating current that the user can use after passing through […]
1. Overall ArrangementWe will take the Infineon FF600R17ME4 IGBT module to explain. First look at its pin definition and internal layout. Note: The internal arrangement of the brown module is actually the corresponding model produced by Fuji, because its package and pin definition are exactly the same. There is no big difference in its internal layout. A. The module is […]

Power supply and other equipment; IGBT module has the characteristics of energy saving, convenient installation […]
1. What is an IGBT? One of the most important components in power electronics is the IGBT. The so-called IGBT (Insulated Gate Bipolar Transistor) is a composite full-regulated-voltage-driven-power semiconductor device composed of BJT (Bipolar Junction Transistor) and MOS (Insulated Gate Field Effect Transistor), which has its own The feature of shutdown. To put it simply, it is a non-on-off switch. […]
