Automotive electronics have gone through several eras of evolution in the past 30 years. From the pure internal combustion engines (ICE) that had mostly mechanical, or engine-driven systems, to the mild hybrid (MHEV) with the addition of electrical motivation, to the fully battery-electric car (BEV). In each of these three eras, the architecture, and even the basic semiconductor components for converting and distributing electrical power changed. This article discusses this evolution and makes some speculations about likely further evolutionary directions.

The EPC2050 offers power systems designers a 350 V, 65 mΩ, 26 A power transistor in an extremely small chip-scale package.  These new devices are ideal for applications such as multi-level converters, EV charging, solar power inverters, and motor drives.

EL SEGUNDO, Calif. — April 2018 — Efficient Power Conversion announces the EPC2050, a 350 V GaN transistor with a maximum R_DS(on) of 65 mΩ and a 26 A pulsed output current. Applications include EV charging, solar power inverters, motor drives, and multi-level converter configurations, such as a 3-level, 400 V input to 48 V output LLC converter for telecom or server power supplies.
