A Field-Programmable Gate Array, or FPGA, is a semiconductor device that can be configured after manufacturing to perform custom digital logic functions. Unlike a traditional CPU, which executes software instructions sequentially, an FPGA contains programmable logic blocks, routing resources, memory elements, and digital signal-processing components that can be arranged into specialized hardware circuits. Engineers commonly…

Hitachi Energy is putting $528 million into a new Mississippi transformer factory as the U.S. power system runs into one of the least glamorous but most consequential bottlenecks of the AI and electrification boom: not enough transformer manufacturing capacity. On September 15, Hitachi Energy announced a new power-transformer manufacturing facility in Gallman, Mississippi. The company…

Today’s foundation is the relationship between voltage, current, resistance, and power. These four quantities show up constantly when troubleshooting power supplies, motors, control circuits, semiconductor equipment, and data-center hardware. Voltage (V) is electrical potential difference. Think of voltage as the electrical force available to move charge between two points. A standard U.S. receptacle should measure…
