Infineon to acquire Cypress Semiconductor for $10 billion
Semiconductor manufacturer Infineon Technologies has acquired Cypress Semiconductor Corporation for $23.85 per share, or about $10.1 billion. The acquisition will add Cypress’s microcontrollers and software and connectivity components, such as NOR flash memories, to Infineon’s portfolio. If approved by Cypress’s shareholders and regulatory agencies, the acquisition is expected to close by early 2020. Reinhard Ploss,… Read more »
SiC vs GaN semiconductors for EV power converters: Tech Opinion
Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
A closer look at the losses in power semiconductors
A previous article examined loss mechanisms in traction motors, which tend to be the single biggest source of losses in a modern EV drivetrain. This time, the focus is on the various power semiconductors, as they are the next biggest source of losses. Also covered in brief are ways to mitigate these losses and design… Read more »
Top causes of failure in power semiconductors
All electronic devices eventually die, and the failure can be quite spectacular if suitable foresight and care was not employed during the design and construction phases, especially if the device handles high power or is supplied by a large battery. It should go without saying that both conditions apply to much of the electronics inside… Read more »
