Here’s why Tesla transitioned to a semi-custom power module design in Model 3 inverter

A closer look at semiconductor packaging considerations in EVs One of the most critical decisions to be made at the earliest stage of designing a new power converter concerns the packages used for the semiconductors, as pretty much every other aspect of the design hinges on their physical form. This is especially true for the main… Read more »

ROHM’s new shunt resistors feature novel high heat dissipation structure

Semiconductor manufacturer ROHM has announced new shunt resistors ideal for current detection in motors and power supply circuits used in EVs and industrial equipment. The GMR50 series of resistors deliver 4 W rated power (at electrode temperature TK=90° C) in the compact 5.0 mm × 2.5 mm (2010 type package) size. Shunt resistors are widely… Read more »

Infineon’s new 900 A IGBT chip offers 30% less static loss

German semiconductor manufacturer Infineon has introduced a new version of its IGBT7 chip in its TRENCHSTOP line that boasts 30% less static loss than previous models. The 1,200 V module provides a leading nominal current of 900 A. Infineon says this enables a 30% higher inverter output current from the same frame size compared with… Read more »

EMC for EVs: Understanding electromagnetic compatibility

Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »
