“Is a feature ,” Aris interrupted, tapping a coil wrapped in a strange, iridescent ribbon. “Active EMI filtering. Instead of suppressing the noise, we sample it, invert it, and feed it back into the gate driver of the GaN device. The noise cancels itself.”

“Efficient chargers for electric aircraft,” Aris said. Power Electronics- Circuits- Devices

“I can’t,” Leo whispered. “The gate driver is oscillating on its own. It’s using the parasitic inductance of the PCB traces as a tank circuit.” “Is a feature ,” Aris interrupted, tapping a

“You’re taking a short-circuit,” Aris replied, and he reached for the main breaker. The noise cancels itself

The story of power electronics was always the same, Aris liked to lecture—though no one attended his lectures anymore. It was a war between three forces: , Efficiency , and Heat . You could have two, never three.
