How do two-level and three-level inverter topologies compare in EVs?
Whenever an electric vehicle (EV) battery bus exceeds 400 V, it poses powertrain design challenges for engineers. One of the key design challenges is the choice of inverter topology, whether a two-level or a three-level inverter topology. Though a three-level inverter has a higher device count, we will discuss in the article where these topologies…
High-current common-mode chokes support EV charging equipment
ITG Electronics has introduced its DCN121107A Series of high-current nanocrystalline common-mode chokes for power electronics applications including electric-vehicle charging equipment. The components are rated for 300 Vac operation and currents up to 36 A. The series is designed to suppress common-mode noise while maintaining low direct current resistance (DCR). Its nanocrystalline core material can reduce…
Quantum-classical model tested for energy forecasting as EV charging adds grid complexity
Silicon Quantum Computing (SQC) and Schneider Electric have progressed to Stage 2 of the Australian Government’s Critical Technologies Challenge Program (CTCP), receiving A$3.6 million (US$2.5 million) in funding to continue their work with UNSW Sydney. As rooftop solar, home batteries, and electric vehicles (EVs) become more widespread, household energy systems are becoming more dynamic and…
Powertrain-in-the-loop testing combines hardware and simulation for EV development
Cambustion has introduced a Powertrain in the Loop (PiL) testing platform at its Hub Dyno facility in the UK. The system combines physical powertrain hardware with simulated vehicle subsystems to begin vehicle-level development before a complete prototype is available. The platform uses Hardware in the Loop (HiL) capability to represent systems that are not yet…
New 200 mm SiC substrate aims to improve power device yields
Wolfspeed has introduced a Premium 200 mm n-type silicon carbide (SiC) substrate designed to improve semiconductor manufacturing yields through lower defect levels and greater wafer-shape stability. SiC power devices are used in high-voltage applications including electric vehicle (EV) traction inverters, onboard chargers, and dc-dc converters. As manufacturers move toward higher voltages and larger die sizes,…
