What it takes to make it real: Opportunities and challenges moving to 1500-V architectures
  Guy Moxey
 Senior Vice President, Business Development and Marketing

Meeting rising power needs is a known challenge for our industry. Consequently, the move to 1500-V DC bus architectures is a necessary trend to solve the need for more power in limited spaces. Pioneered by the solar industry, it is now proliferating into wind-power applications, mega-watt charging, and big battery-electric vehicles (BEVs). But is the power electronics supply chain ready to meet the growing trend? In this presentation, we will take a realistic look at the complete ecosystem needed to support the move to 1500-V applications and address the bottlenecks on this transition’s way.

Soft-switching for Automotive Traction Inverter Applications
  Dr. Ajay Poonjal Pai
 Director of WBG Innovation & Application Engineering
 Sanan Semiconductors
With the increasing adoption of battery electric vehicle (BEV), there is an ever increasing focus on their driving range in order to reach an optimum cost-performance ratio. Traction inverter and motors consume over 30% of the overall electrical losses in a battery electric vehicle (BEV). Therefore, optimizing them is important. Due to their unipolar behavior, SiC Mosfets help in reducing power losses by over 50% typically compared to IGBTs. However, the high switching speeds of SiC can seldom be reaped due to system constraints, e.g., dv/dt slew rate limitation due to the motor winding insulation, leaving a significant potential untapped. This talk presents these system-dependent challenges limiting the full-utilization of SiC. An advanced inverter topology is presented which can help to overcome the classical trade-off between switching speed and dv/dt slew rate. This topology also offers soft switching, which helps to significantly reduce switching losses. As a result, an inverter system efficiency of over 99% is reached.

Utilizing Physics-Based AI-Powered Digital Twins to Accelerate Design Optimization and Manufacturing Yield of SiC Power Devices
  Dr. Josef Weinbub
 Advanced R&D Program Director
 Silvaco
SiC technology is increasingly being adopted in the EV and industrial markets, demonstrating a significant improvement in performance. However, SiC must remain cost-competitive against incumbent silicon-based technologies and meet stringent time-to-market and volume requirements at high yield. While the use of physics-based modeling (e.g., TCAD) and design simulation tools is common within device technology R&D teams, product and process engineers often rely heavily on empirical data as they productize SiC devices and bring them to manufacturing. Silvaco aims to unify these efforts through its Fab Technology Co-Optimization™ (FTCO) platform. With FTCO, experimental data and physical simulation data are used in tandem for realizing a calibrated and iterative AI-powered nonlinear modeling flow to generate a digital twin. The ultimate goal of integrating the FTCO platform into an organization is to develop and deploy such a physics-based digital twin representative of the fab. A digital twin allows for interactive structure modeling and virtual experimentation, shortens learning cycles and is user-friendly, enabling engineers not traditionally using physics-based simulation tools to benefit from the insights provided.

Enhanced laser annealing for ohmic contact formation for SiC power devices
  Maurice Clair
 Team Leader Technology and Innovation Management
 3D-Micromac
The evolution of silicon carbide (SiC) power devices has driven demand for advanced manufacturing techniques that enhance device performance and efficiency. A critical stage in this process is Ohmic Contact Formation (OCF), which establishes reliable ohmic contacts on SiC materials, enabling efficient current flow. Traditional rapid thermal processing (RTP) methods for OCF now face limitations as SiC devices become thinner and more complex. This presentation will explore the advantages of laser-based thermal annealing as an alternative to RTP for OCF, highlighting how laser technology meets the unique demands of SiC-based power device fabrication and pave the way for more efficient, reliable electronics in high-performance applications. The presentation will focus on the precision, repeatability, and high throughput achievable through laser annealing systems like 3D-Micromac’s microPRO XS OCF, which supports consistent device quality. It will show which role sophisticated process routines and an optimized chamber layout play in reducing particle generation and how individual adjustable laser spot profiles enable the processing of different material compositions.

Accurate SiC Simulation in SPICE and PLECS
  Dr. Didier Balocco
 Technical Marketing Engineer
 onsemi
SiC is still a relative new material. Every new generation brings more performances to improve system or application efficiency. But, to compare or evaluate the advantage to move on, designer need tools to compare at system level the benefits. SPICE, invented in the 70’s, doesn’t know SiC material and specific characteristics. onsemi build all SiC physical equations to describe SiC operation and implement then in SPICE. With such powerful SPICE models, accurate simulation results can be obtained. For every designer, losses are the focus. As we will see in this session, onsemi SPICE models can predict then if the environment is also modeled. The drawback of SPICE is the simulation time need for big system. PLECS overcomes this by using a state change technic and models including precalculated losses. As it will be demonstrated in the previous section on SPICE, system losses don’t depend only on active devices. There are interactions between active and passive devices, influencing each other’s. For this, onsemi bring a new tool : the “Self-Service PLECS Model Generator” in complement with the “Elite Power Simulator” tool, a system simulation platform based on PLECS. The model generator objective is to predict accurately the losses by including in the PLECS models the system environment and interactions between each design specific passive and active parts. The second section will show examples and comparisons between SPICE results and PLECS results. It will prove the superior accuracy of using the model generator to predict system losses.

2nd Generation 1200 V SiC MOSFET: Robust against Radiation and Better in RDS,on
  Hadiuzzaman Syed
 Developer- Power Semiconductor (Silicon Carbide) / Power Module
 Bosch
One of the concerns regarding the reliability of SiC based power modules in an EV inverter is its resilience to terrestrial neutron radiation. As the battery voltage of the EV is increasing, the probability of a neutron induced catastrophic failure (SEB) of the SiC based switches is also increasing. A terrestrial radiation rugged SiC switch traditionally employs higher breakdown voltage, increasing the device on state resistance (RDS,on). Bosch 2nd Generation 1200 V SiC MOSFETs employ a two degree optimization technique in the device design that improves radiation ruggedness without affecting the device RDS,on. The presentation will discuss the experimental results of the Generation 1 and 2 devices and the resulting FIT rate based on an EV mission profile. The Generation 2 devices enable the power module to achieve below 1PPM failure rate related to the neutron radiation and 20 percent reduction of the on-state resistance compared to Generation 1.

SiC MOSFET with high temperature stability
  Dr. Georgio El-Zammar
 SiC Senior Development Engineer
 Nexperia
Silicon carbide (SiC) MOSFETs are typically characterized by their RDS(on) values measured at 25°C, with this temperature reflected in device naming conventions. However, in real-world applications, these MOSFETs often operate at higher temperatures due to power losses, leading to an increase in RDS(on). The rise in RDS(on) with temperature can significantly affect the overall efficiency of the application. Therefore, understanding and ensuring the temperature stability of RDS(on) is crucial for optimizing performance. This presentation will explore the impact of RDS(on) temperature stability on application efficiency and why it is a critical factor in power electronics.
