: In 1956, a team at General Electric , led by J. Moll, invented the thyristor (silicon-controlled rectifier). This sparked the "second electronics revolution," replacing large mercury valves with compact silicon wafers that could switch heavy loads.

The story of Power Electronics is a century-long transformation that turned electrical engineering from a field of bulky, mechanical switches into a sophisticated "muscle and brain" system that powers our modern world. The Dawn of Power Conversion (1900–1950s) Download Power Electronics (1) pdf

: These early, glowing vacuum devices allowed for the electrification of railways and early industrial processes, though they were limited by their massive size and low reliability. The Semiconductor Revolution (1956–1980s) : In 1956, a team at General Electric , led by J
