1. How does IGBT work?
IGBT is composed of N-channel MOS (Metal Oxide Semiconductor) field effect transistor and PNP bipolar transistor. It combines the advantages of MOSFET and bipolar transistor, with lower on-state voltage drop when on and higher breakdown voltage when off. Its working principle is as follows:
（1）On state:
In the on state of IGBT, when the control voltage Ugs is greater than the gate threshold voltage Uth, the N-channel MOSFET is in the on state, forming a channel, and the current can flow from the collector to the source. Since the on resistance of the N-channel MOSFET is small, the voltage drop when it is turned on is very small.
（2）Off state:
When the control voltage Ugs is less than the gate threshold voltage Uth, the N-channel MOSFET has no channel and is not conductive, and the IGBT enters the off state. At this time, the IGBT can be turned off by controlling the voltage Uce (collector-emitter voltage). Due to the presence of the PNP bipolar transistor, the IGBT can withstand higher voltages even under higher Uce.
The working principle of the IGBT can be explained by the example of a self-locking switch. The N-channel MOSFET is equivalent to the door lock of the self-locking switch, and the state of the door lock can be controlled to achieve on and off; the PNP bipolar transistor is equivalent to the key of the self-locking switch. Even in the off state, as long as the key is inserted (providing a higher Uce), the switch can still be opened. -
2. What are the application fields of IGBT?
The main application areas of IGBT power semiconductors include:
(1) Motor control: In the field of motor control, IGBT, as the core device of the inverter, can convert DC power into AC power with adjustable frequency, thereby driving the motor for precise control. Whether it is a large motor on an industrial production line or a drive motor in a new energy vehicle, it is inseparable from the support of IGBT. In addition, IGBT also plays an important role in the high-power DC/AC inverter of the electric control system and is the key to achieving efficient operation of the motor.
(2) Power electronics: IGBT is one of the core devices in the field of power electronics and is widely used in various power supply, battery charging, power management, power conversion, power regulation, power protection, power filtering, power distribution, power control and power monitoring systems.

4. What is the difference between terminals and connectors?
We often hear the terms "terminal" and "connector." While both play a key role in electrical connections, there are distinct differences between them.
I. Definitions and Differences between Terminals and Connectors
1. Definition
Terminal: A terminal generally refers to a piece of metal used to make electrical connections. It is typically used to connect wires from outside a device to the inside of the device to transmit current or signals.
Connector: A connector is a device used to connect two active components, capable of transmitting current or signals. It typically consists of a plug and a socket.
2. Differences
In terms of structure and function, terminals serve more as an access point or interface for internal and external electrical connections, while connectors focus on electrical connections between two devices or components. In other words, terminals are often the starting or ending point of an electrical connection, while connectors serve as the bridge connecting the starting and ending points.
II. The Importance and Applications of Connector Terminals
Connector terminals play a crucial role in electrical systems. They not only ensure the smooth transmission of current but also guarantee the stability and safety of the electrical system. Connector terminals are widely used in various electrical devices, including household appliances, automotive electronics, and industrial automation.
Take automotive electronics as an example. With the increasing electrification of vehicles, connector terminals have become critical components for ensuring the proper functioning of various electronic systems. From engine control units to in-car entertainment systems, ubiquitous connector terminals provide a solid foundation for the stable operation of the entire vehicle.
