TOKYO, February 20, 2023 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that itentered into a share transfer agreement on February 16 to wholly acquire Scibreak AB, a Swedish-based
company that develops direct current circuit breakers (DCCBs). The two firms aim to strengthen thecompetitiveness of their unified business by working closely on developing DCCB technologies for highvoltage direct current (HVDC) systems to support the increasing global deployment of renewable energy.
Purpose of Acquisition
The introduction of renewable energy generation, such as wind power, is increasing worldwide to achievecarbon neutrality. Particularly in offshore wind power generation, HVDC is used for long-distancetransmission between offshore and onshore load centres, as it offers lower power losses and cost whencompared to AC transmission. In the future, multi-terminal HVDC networks are expected to develop,

particularly for offshore wind power generation in Europe, allowing for efficient cross-border energy
transmission. These networks will require DCCBs, which will play a critical role in protecting the powersystem.
HVDC breakers will require very fast operation times, in the order of a few milliseconds, and companies arestepping up technological development in response to the need for more compact, high-performance, and costeffective DCCBs.
Scibreak has market leading DCCB technology, in terms of operation time and footprint. Through theacquisition of shares, Mitsubishi Electric will utilise Scibreak’s technology and know-how to lead the market
commercialisation of DCCBs, strengthening its global HVDC system business and contributing to therealisation of carbon neutrality through the further spread of renewable energy.
