Infineon announced on the 13th that it has launched the XHP™ 2 CoolSiC™ power module, which supports a maximum DC link voltage of 1500V.

With the recent expansion of renewable energy, the increasing voltage of power conversion systems is becoming a major trend. This is because higher voltage allows for a reduction in current, thereby improving system efficiency. Consequently, there is a growing demand for power semiconductors that operate stably even in high-voltage environments.

This product is characterized by the application of a silicon carbide (SiC)-based 2300V MOSFET, which simultaneously reduces switching losses and conduction losses compared to existing silicon devices. It offers on-resistance (RDS(on)) of 1mΩ to 2mΩ and 4kV or 6kV isolation voltage options, and is designed to facilitate parallel configuration through a symmetric switching structure.

These technical characteristics lead to improved efficiency and miniaturization at the system level. Inverters can operate at higher switching frequencies to reduce harmonics, and allow for reduced equipment size or increased power density based on the same output.

Applications include high-voltage-based renewable energy facilities such as wind, solar, and battery energy storage systems. The standardized XHP 2 package is designed to balance performance and efficiency according to various application requirements.

In addition, durability against thermal and mechanical stress was ensured by applying .XT interconnection technology, and the assembly process was simplified and thermal performance consistency was maintained through the option of pre-coated thermal conductive interface material (TIM).

The improvement effect was also confirmed in actual performance verification. In the wind power demo system, a power density of 300 kW/L was achieved, and in the battery storage system test, semiconductor losses were found to be less than 0.7% of the total output. This is interpreted as an indicator showing that efficiency improvement and loss reduction are possible simultaneously in high-voltage power conversion systems.
