The story

The Dynex power semiconductor business was originally established in Lincoln over 50 years ago when it was known as AEI Semiconductors Ltd. At that time, the business introduced some of the first silicon-based power semiconductor components in the world. Since then it acquired the power semiconductor interests, technologies and products from some major names such as GEC, SGS-Thomson, Alstom and Marconi Electronic Devices (MEDL).

Chinese takeover

In 2008, 75% of Dynex Power shares were acquired by Chinese manufacturer Zhuzhou CSR Times Electric Co., Ltd., a subsidiary of CSR Corporation Limited. A 2018 report in The Sunday Times asked if this acquisition led to China using British technology to build a railgun.
