Topdiode 600V-650V IGBT, 1200V-1350V IGBT used on Welding Machine

During the working process of waveform welding and cutting equipment, a smoother DC current is obtained after correction and excitation by the bias circuit or single-phase 50Hz power frequency alternating current. The DC voltage of the waveform generator composed of IGBT or field effect tube is 15 to 100kHz. The alternating current, after being stepped down by the intermediate frequency main transformer, is corrected again to obtain a stable DC output current (or inverted again to output alternating current of the required frequency).

The control circuit of the inverter welding and cutting equipment consists of a given circuit and a drive circuit. By processing the feedback of voltage and current signals, the whole machine cycle control is realized, and pulse width modulation (PWM) is used as the core control. technology, thereby obtaining the constant current characteristics of fast pulse width modulation and excellent welding and cutting process effects.

What is IGBT?

IGBT stands for insulated-gate bipolar transistor. It is a power transistor that combines an input MOS and an output bipolar transistor.

How an IGBT Works?

Here’s a brief explanation of how an IGBT works:


  1. Basics: An IGBT is made up of two main components – a P-type semiconductor and N-type semiconductor. These semiconductors are made of materials such as silicon, and they are joined together to form a p-n junction, which is the basic structure of a diode.
  2. Gate: The gate of an IGBT is an electrode that is used to control the flow of current between the p-type and n-type semiconductors. It is insulated from the rest of the device by a layer of Aluminum oxide or Silicon nitride, which prevents leakage current and ensures that the device operates only when the gate signal is applied.
  3. Bipolar: The term “bipolar” refers to the fact that the IGBT can conduct both positive and negative currents, unlike a uni-polar device such as a MOSFET, which can only conduct positive current. This allows the IGBT to handle higher power levels and operate more efficiently in certain applications.
  4. Operation: When the gate signal is applied, the IGBT is turned on, and current can flow between the p-type and n-type semiconductors. The amount of current that flows depends on the voltage applied to the gate and the resistance of the load connected to the IGBT. When the gate signal is removed, the IGBT is turned off, and no current can flow.
What are Features of IGBT?

Some of the key features of IGBT include:

  1. High voltage and current handling capabilities: IGBTs can handle high voltage and current levels, making them suitable for use in high power applications. They can switch and control large amounts of power, making them an excellent choice for use in electric vehicles, solar inverters, and wind turbines, among other applications.
  2. Fast switching speed: IGBTs can switch on and off very quickly, which allows them to be used in high-speed applications such as power converters and motor controllers. Their fast switching speed also helps to reduce energy losses and improve overall system efficiency.
  3. Low conduction losses: IGBTs have low conduction losses, which makes them more energy-efficient than other types of power semiconductor devices. This feature is particularly important in applications where the device is required to conduct high currents for extended periods of time.
  4. High efficiency: IGBTs can achieve high efficiency levels in power conversion and control applications due to their low losses and fast switching speed. This feature is beneficial in applications where energy efficiency is a critical concern, such as in electric vehicles and solar inverters.
  5. Compact size: IGBTs have a smaller physical size compared to other types of power semiconductor devices, making them more suitable for use in compact and space-constrained applications. This feature is particularly important in applications such as aerospace, military, and transportation, where size and weight are critical factors.
What are Applications of IGBT?
