The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »

Sensata develops new i-BMS battery management system for applications up to 60 volts
Sensata Technologies debuted a new battery management systems at the Battery Show North America in Novi, Michigan. The new i-BMS battery management system from Sensata acquisition Lithium Balance is a cell chemistry-agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60 V, such as two-wheelers, three-wheelers, automated guided vehicles (AGVs) and… Read more »
A closer look at humidity control methods for EV electronics
It’s a well-known trope that water and electricity don’t mix, but keeping the two separated is often deceptively difficult, because the simple solution of just sealing the box is insufficient on its own. This is because of condensation, which can come from water vapor in the air at the time the box was sealed, or… Read more »
Nexperia acquires Newport Wafer Fab
Semiconductors have been enjoying an unaccustomed turn in the media spotlight since the recent shortage that forced many automakers to slow or suspend production. The latest news on the semiconductor scene is that Nexperia, an expert in the high-volume production of essential semiconductors, has acquired Newport Wafer Fab, which operates a semiconductor production facility in… Read more »
