DC/DC converters are key elements of electrified powertrain delivering the necessary power on-demand at the right voltage. The multiplicity of types (HV/HV, HV/LV), isolated or not, mono-directional or bidirectional, and the diversity of power topology push designers to select a digital controller versatile and powerful enough to address all configurations.
But a new generation of DC/DC converters is required to offer higher power density and best efficiency while supporting higher voltage (up to 900V). This next generation of DC/DC converter will use wide bandgap power devices, such as SiC and GaN, that allow faster switching frequency while limiting switching losses, and open the path to the downsizing of the passive components and the reduction of the cooling constraints. And, as power is nothing without control, a new generation of the digital controller is required as well.
Join this webinar at next week’s Virtual Conference on EV Engineering, presented by Silicon Mobility, where you will learn how Silicon Mobility’s OLEA T222 FPCU and OLEA LIB, its control software library, enable the design of efficient, safe, and high-power density DC/DC converters. The unprecedented processing capability of OLEA will be covered including its ability to run at a high-speed demanding current control loop (peak current mode control up to 500kHz), on several phases in parallel and independently (up to 6 phases) and with high switching frequency (up to 500 kHz).
We will go over different use cases around the most popular power topologies such as Phase Shift Full-Bridge, Multi-Phase, and Full-Bridge LLC Resonant.

Ultrasonic Metal Welding Applications In EV-TelsoCar
The dynamic development of new electric vehicles and batteries present ongoing challenges and opportunities. Ultrasonic welding technology is a proven joining process that is increasingly specified by carmakers for use in EV for cable to terminal connections, bus bars, battery manufacturing and power electronics.
In this webinar, Greg Ruscak, Telsonic’s Applications Manager will provide an overview of several ultrasonic welding applications currently used in EVs. The presentation explains details of each application as well as the innovative and exclusive technology that Telsonic utilizes to provide the best quality joining solutions. The demonstrated applications will explore the capabilities of conventional ultrasonic linear welding as well as the exclusive Telsonic Torsional SONIQTWIST® and PowerWheel® technology.
EV Battery Module Design: A Real-World Cloud-Powered Simulation Case
EV manufacturers need to design for a wide range of battery operating conditions and cooling strategies under the tight deadlines dictated by the growing requests of the electric mobility market. Designing the right solutions, while reducing the need for lengthy and costly physical prototyping, calls for modern simulation tools that don’t require time-intensive manual setup and are not hindered by computational limitations of traditional CAE tools. By adopting simulation tools born in the cloud, the full simulation workflow is shortened from days, sometimes weeks, to hours enabling engineers to explore the full design space and reduce the need for testing.
In this session, we explore the thermal performance of a liquid-cooled battery module by Rimac using cloud-native engineering simulation. Alexander Fischer, co-founder and product manager at SimScale, investigates how the change in different design parameters influences the temperature of battery cells inside the module with the goal of increasing battery life by maintaining an optimal operating temperature distribution. By simulating in the cloud, engineers can run hundreds of design iterations in parallel with the desired accuracy and get design insight in a timely fashion.
Broadcast live April 4 – 7, 2022, the conference content will span the EV engineering supply chain and ecosystem including motor and power electronics design and manufacturing, cell development, battery systems, testing, powertrains, thermal management, circuit protection, wire and cable, EMI/EMC and more.
