High-frequency switchmode power conversion technology has been in use in nearly every segment of the economy, including demanding aerospace and military power systems that must function despite the harshest physical and electromagnetic environments any technology must endure.
Yet many power utilities and industrial applications have been slow to switch from 1950s-era SCR technology to the only slightly newer switchmode technology. This is despite the overwhelming advantages of switchmode technology in size, weight, performance cost, efficiency, and even standards compliance (energy efficiency regulations mean that SCR chargers have been illegal for sale in California and Oregon since 2017).
Bill Kaewert, CEO of SENS, explored switchmode vs SCR, including:
