The Namesake of Power Systems Design

Jason Lomberg, North American Editor, PSD

­Welcome to the November issue! With the Spooky Season (and The Battery Show) behind us, we’ve now entered the home stretch of 2025, along with Thanksgiving, the unmitigated horror of Black Friday, and the holidays (and my son’s birthday) to close out the year. Of late, one of the biggest news sto

­Not all modern electronics require increased power density. But it’s safe to say that getting more power out of power supplies with equivalent or smaller weights and volumes is of near universal interest in the design world, regardless. Switch Mode Power Supplies Switch mode power supplies (SMPS) are on

­The two established architectures of silicon carbide (SiC) MOSFETs for high-power systems – planar and trench – both present a fundamental unappealing compromise for power engineers. The manufacturing simplicity of the planar gate structure enables increased yields and therefore lower costs. This stru

Figure 1: Block diagram of a solid-state circuit breaker

­A circuit breaker is a device used to protect electrical circuits from damage caused by overcurrent, overload, and short circuits. An electromechanical breaker (EMB), the de facto standard, consists of two separate triggers: bimetal, which is slow and tripped by overcurrent, and electromagnetic, which is fast an

Will America Tinker with Taiwan's

Jason Lomberg, North America Editor, PSD

­The Trump Administration is pressuring Taiwan to quickly move half of its semiconductor production to the U.S. or risk losing American military protection. And no, this isn’t the domino that leads inexorably to World War 3 (probably), but it does throw into sharp contrast the so-called “Silicon Shield” an
