CurrentPre-Switch is bringing to market a disruptive power conversion technology that promises unrivaled gains in power converter efficiency, size and cost reduction, and EV car range extension. Since the introduction of transistorized power converters in the early 1960s, engineers have been challenged by the confining limitations of hard-switched transistor losses. Promising cost and size reductions enabled by faster switching speeds have been limited by increases in unwanted heat, wasted energy and expensive heat extraction methods. As a consequence, even the best power converters used today in motor drives, wind turbines, solar inverters, E-mobility, and others are still hindered by slow switching frequencies.The key to breaking through the 50-year-old hard-switching innovation barrier has been a promising technology known as "soft-switching". Past soft-switching technologies worked modestly but remained ineffective for the vast majority of power converters because they stopped soft-switching under real world conditions of varying input and output. Pre-Flex AI is our embedded AI technology which enables accurate soft-switching across any varying input and output condition while automatically compensating for variances in manufacturing and device tolerances. Our technology is simply implemented with minimal external component costs and is available in chip, controller board and gate driver board options. The results are staggeringly positive. Pre-Flex AI eliminates 70-80% of IGBT and 90-95% of SiC & GaN MOSFET switching losses. Equally important, our architecture dramatically reduces the dV/dt and EMI associated with the increased switching speeds. Pre-Switch has broken through the 50-year-old hard-switched innovation barrier. Soft-switching is the future of power conversion and the world will adopt our technology.We are Pre-Switch, Inc. We are simple, elegant and cost effective soft-switching technology for the masses. We take the HARD out of switching.
