Since 1974, when Yaskawa shipped the world’s first a small general-purpose transistor inverter (AC drive), total shipments of AC drive reached 30 million units in 2021. We have developed many world’s first technologies such as vector control, digital control, IGBT (Insulated Gate Bipolar Transistor) drive, and AC/AC conversion. These technologies have become widely accepted as the de facto standard, making life more convenient for people around the world and contributing to increased productivity and energy conservation at factories.
