Toshiba's high-power device IEGT's century-long journey (Part 2)

Since the beginning of the 21st century, Toshiba's high-power devices have been widely used in various scenarios due to their irreplaceable superior performance.

IEGT is commonly found in various high-power drive equipment and flexible DC transmission scenarios.

As a common packaging form of IGBT modules, PMI is widely used in high-speed railways, electric locomotives, subways and light rails due to its good heat dissipation and insulation properties.

Some application examples of PMI

As market demand continues to increase, high-power, miniaturized, and energy-efficient high-power devices have become the new favorite. PPI, which has high reliability and high power density, has been successfully applied to many key projects of flexible DC transmission.

Some examples of PPI applications

PPI is used in the world's highest capacity flexible DC transmission project

（±350kV，1000MW）

PPI Press-fit IEGT - Toshiba has invented and developed a variety of high-power devices so far, and now focuses more on IEGT.

Under the policy call of "accelerating the revolution of energy production and consumption and enhancing my country's energy self-security", my country's offshore wind power and high-performance transmission are developing rapidly. The market has higher and higher requirements for the density and reliability of converter power meters, and Toshiba's press-fit IEGT power unit solution is suitable for high-power converters, which can effectively achieve energy saving of high-power converters and fully meet the new market demands of high power, miniaturization, high efficiency, energy saving and environmental protection.

PPI press-fit package IEG T - uses internal leadless bonding technology and double-sided water cooling to significantly improve the power density and reliability of the entire system, and can reduce the size of the equipment and reduce the floor space. It is a well-deserved leader in the new energy field.

The unique advantages of PPI devices give it a broader development prospect than in the past. In the future, Toshiba will continue to strengthen its advantages and continue to develop products with higher current and higher voltage.

For example, a single device can achieve 4.5kV / 4kA current capacity in the same package as a 4.5kV / 3kA device . Customers can use the previous design to upgrade the capacity of the product by adopting the new generation of PPI; while maintaining the high current capacity, the voltage resistance of a single device can be upgraded. Customers can use fewer devices to achieve the same voltage level product.
