Overview

Hitachi ABB Power Grids - Semiconductor is known for its high-reliability power semiconductors that support medium and high-voltage applications. For example, IGBTs implemented in the main traction chain of rail rolling stock, press-pack devices used in high-voltage direct current distribution (HVDC) or other transmission and distribution (T&D) applications, and various power semiconductors running in industrial applications. Building on its experience of high-performance, high-reliability devices for voltages above 3.3 kV, Hitachi ABB Power Grids is now expanding to lower voltages.

This webinar examines the use of power semiconductors in a low voltage drive, applying our devices at the front-end line-side and machine-side converters. The front-end converts an AC voltage to DC and supplies it to the DC link. Depending on the operating scheme, diodes, thyristors, or even IGBTs might be used for this application. Typically, products such as Hitachi ABB Power Grids Semiconductors' 60Pak diode and thyristor modules are needed because they feature industry-standard housings and very low losses together with the highest operating temperature. For the active front-end or the machine-side converter that connects the DC link to the motor, LoPak modules are a common choice. These LoPak modules are now also available with pre-applied TIM, helping to increase reliability over the drive's lifetime.

Key Takeaways

  • Examine the use of power semiconductors in a low voltage drive
  • Learn the advantages of medium power semiconductor devices and their performance
  • Understand trends and see examples of future developments
