According to a recent study by Polaris Market Research, the global IGBT & thyristor market was valued at USD 5.80 billion in 2024 and is projected to grow at a CAGR of 4.45 % from 2025 to 2034.
In today’s world, there is a demand for electronic devices and power systems to be increasingly faster, smarter, and more efficient. From the automotive industry to renewable energy, managing high-power with precision and reliability is always in demand. Behind this advancement are key components that make it possible: IGBTs and thyristors, which play an important role in controlling and converting electrical energy.
What are IGBT and Thyristor?
The IGBTs and thyristors control and switch high levels of electrical power. Their key use has been in safely and efficiently managing power within machines, power systems, and most electronic devices.
How do IGBT & Thyristor Work?
IGBTs encapsulate the strengths of two different types of transistors. They have the high-speed switching of a MOSFET and the high-current-handling capabilities of a bipolar transistor. When a voltage is applied to the gate of an IGBT, it conducts current; when the voltage is removed, it stops conducting current. In this simple control lies the key to its use for efficient power management.
Thyristors work a little differently. They remain off until a small voltage is applied to their gate. They then continue to conduct electricity until the main current drops to zero. This makes them suitable for applications where high-power switching must be reliable, even if speed is not critical.
Where are IGBT and Thyristor Used?
Most modern systems that move, convert, or control power use IGBTs or thyristors. They facilitate the smooth and safe operation of these systems. Some key application areas are given below.
Power Electronics
The IGBT device is widely used in inverters and converters. They switch power fast to help reduce energy loss. Thyristors are used in rectifiers and power controllers; they handle high power in large systems.
Automotive
IGBT devices are common in electric cars; they manage the motor, helping control the battery system. Thyristors are used in older or heavy-duty vehicles where high power handling is required.
Renewable Energy
IGBT devices are used in solar inverters and wind converters, enabling the conversion of raw energy into usable power. Thyristors support large grid systems and protect them during high-load conditions.
Industrial Machines
Factories use both devices in big motors, welding units, and heating systems. IGBT devices offer fast control. Thyristors handle long hours of heavy power.
Home and Consumer Devices
IGBT devices are used in everything from air conditioners to induction stoves, helping ensure safe power regulation and efficiency. Thyristors have been used in simple dimmers and basic power controls.
Key Driving Factors of IGBT & Thyristor Market
- The expansion of smart grids and energy storage increases demand for IGBT and thyristor devices, as advanced power networks require stable, efficient power control.
- New materials such as silicon carbide and gallium nitride improve power device performance, encouraging companies to adopt better, more efficient designs.
- As industrial automation rises, factories are using more robotics and smart machines, thereby increasing demand for devices that manage power in heavy machinery.
- Electric vehicle adoption is rapidly increasing, and most EV systems depend on these devices for motor control, charging, and power conversion applications, thereby driving significant market demand.
What are Advantages of IGBT and Thyristor?
IGBT and thyristor devices offer several significant advantages in power systems. IGBT devices switch quickly and efficiently. They reduce heating and generally improve the performance of machinery and power units. They also work quite well in compact designs, which makes them a good choice for modern devices.
They also have their own strengths: thyristors can withstand very high power and tend not to fail easily. They are robust, steady, and reliable in harsh conditions. In these applications, thyristors are used in heavy industrial machinery and large power networks. Both devices support electrical safety; hence, both are used in many systems today.
Conclusion
Demand for IGBT and thyristor devices is increasing as industries move toward cleaner energy and smarter power systems. These devices support safe, efficient power control in many applications. With growing usage in EVs, renewable energy, and industrial equipment, they will remain key in powering the future of power electronics.
