Power stages is a product category rather than a specific brand, commonly associated with industrial power electronics. These components are typically produced by companies specializing in automation, motor control, and energy conversion systems. Major manufacturers like Siemens (Germany), Bosch Rexroth (Germany), or Yaskawa (Japan) develop power stages for applications such as servo drives, frequency converters, and renewable energy systems. These modular units often integrate IGBTs, gate drivers, and cooling solutions to manage high-voltage power conversion in manufacturing, robotics, and energy infrastructure. Distributors like Radwell and Grainger categorize them under industrial automation or motor control sections.
