Silicon carbide is a hot topic in the power electronics field these days. As a recent article in the New York Times explains, SiC is a wide-bandgap (WBG) material that designers are increasingly choosing to make power electronics devices more efficient. WBG advantages The WBG classification has profound implications for device behavior and performance. This… Read more »

Simplifying Automotive Emergency Power Supply Architecture
In this presentation, we will review the low voltage power architecture used in automotive traction inverters. This power source drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This last requirement represents a special challenge as it means the Emergency Power Supply… Read more »
Simplifying EV traction inverters emergency power supply architecture
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 »
InnoSwitch3-AQ supports EV designs with expanded 30-1,200 V input range
Power Integrations has expanded its InnoSwitch3-AQ family of devices, which combine a MOSFET, primary and secondary controllers and Fluxlink reinforced isolated feedback into a single IC. The new family members feature a 900 V primary MOSFET, which is designed for safe and reliable operation during system voltage transients while reducing the number and cost of… Read more »
IC Solutions For Safe And Reliable Propulsion Inverters
In this session, we will review the trends affecting the design of traction inverters, the challenges imposed by the migration towards higher bus voltages, and the need to meet ISO26262 “functional safety”. The changes required to support high-voltage SiC MOSFET switching modules will also be examined. New IC solutions that enable effective and efficient isolated… Read more »
Smart Charging For Smart Buildings: Embracing Load Management
As electric vehicle adoption accelerates, the real estate industry faces increasing pressure to provide efficient charging infrastructure for tenants and customers. However, concerns about grid stability arise as more people plug into Level 2 chargers at these buildings, leading to higher electricity consumption overnight. To address these challenges, future-proof their buildings, and find solutions for… Read more »
Polestar to demonstrate StoreDot’s extreme fast charging battery technology in a prototype EV
Battery innovator StoreDot is collaborating with Polestar on an engineering project to demonstrate how StoreDot’s XFC battery cell technology can be applied to an existing platform, and show what a production-level solution could look like. Following Polestar’s investment in StoreDot, the two companies are working to demonstrate StoreDot’s production-ready XFC technology at full scale in… Read more »
BMW, Ford and Honda to create new company to facilitate EV grid services
In September, BMW, Ford and Honda agreed to form an equally owned company named ChargeScape to create a platform connecting electric utilities, automakers and interested EV customers. It is expected to be operational early in 2024. ChargeScape is designed to increase the value EVs can provide to the electric grid and to enable EV customers… Read more »
Packaging second-life EV batteries into a plug-and-play energy storage system
Q&A with Smartville CEO and co-founder Antoni Tong What do EV batteries have in common with athletes and politicians? Once they age out (or get voted out) of their positions, they have the opportunity to have a lucrative (and in the case of batteries, useful) second career. Repurposing depleted EV batteries for stationary storage applications… Read more »
Juxta pitches its micro-retail stores to EV charging operators
It’s a maxim in the retail fuel trade that the gas brings in the customers, and the sodas and chips bring in the profits. Many expect the same equation to prove true once electrons replace distilled dinosaurs. JUXTA combines this concept with the trends toward self-checkout and rapid deployment. The JUXTA Nomad is a pre-assembled,… Read more »
