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. […]

Temperature control is one of the key factors for the effective operation of MOSFET or IGBT module. Although some MOSFETs are equipped with an internal temperature sensor (body diode), other methods can also be used to monitor temperature. The semiconductor silicon PTC thermistor can perform current control well, or the platinum-based or niobium-based (RTD) resistance […]

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 […]

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 […]

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 […]

IGBT basic application IGBT It is a device composed of a MOSFET (input stage) and a PNP transistor (output stage). It has the characteristics of small driving power and fast switching speed (control and response) of MOSFET devices, and bipolar device saturation. The voltage is reduced and the capacity is large (the power stage 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 […]

Explore IGBT module desaturation and protection techniques, including Vce monitoring, soft turn-off, and active clamping, ensuring safe and reliable short-circuit management.

IGBT module inverter circuit design for solar photovoltaic power generation (1) Solar photovoltaic power generation harnesses sunlight to convert solar energy into electrical energy using solar arrays, specifically PV module squares. The generated direct current (DC) is then transformed into alternating current (AC) through an inverter for user consumption. Traditionally, photovoltaic power generation systems employed […]

First of all, it should be explained that SiC can also be used as an IGBT Module. There is a problem with the Mosfet of Si material, that is, the chip will become thicker if the voltage withstand capability is high, and the conduction loss is also very high. Therefore, the Mosfet of silicon material […]
