Rising EV Demand Drives Onboard Charger Discussion
As the number of electric vehicles (EVs) on our roads increases, the pressure to expand the existing charging infrastructure will also increase. Ideally, this expansion should exceed the current ratio of EVs to charging points and achieve a maximum of no more than 10 EVs per charging point (PCP). Range anxiety is still seen as an obstacle, preventing potential EV owners from transitioning to e-mobility. Increased proliferation of charging points will be a crucial reassurance in the future EV landscape.
In this article, we will outline the various charging systems and focus on the principal semiconductor solutions that help control and distribute the power needed within them. We will outline the role that onboard chargers (OBCs) have to play, and discuss how future trends and advancements in EV charging are facilitating the wider worldwide adoption of the EV.

SiC & GaN Solutions
The landscape of transportation is undergoing a transformative shift towards sustainability and efficiency, driven by the urgent need to address environmental concerns and reduce reliance on traditional fossil fuels. In this paradigm shift, Silicon Carbide (SiC) and Gallium Nitride (GaN) are emerging as pivotal technologies, playing a crucial role in propelling vehicle electrification to new heights. As the automotive industry seeks innovative solutions to enhance the performance and efficiency of electric vehicles (EVs), SiC and GaN are standing out as key enablers that are revolutionizing power electronics and pushing the boundaries of what electric vehicles can achieve. This area explores the transformative impact of SiC and GaN on vehicle electrification, shedding light on their unique properties and applications that are reshaping the future of sustainable mobility.
What are the main benefits of WBG (wide bandgap) materials?
1) Higher Efficiency: WBG materials offer superior electronic properties, allowing for reduced power loss in a wide range of switch-mode applications.
2) Faster Switching Speeds: WBG devices have significantly faster switching speeds compared to traditional silicon devices. Enables higher-frequency operation, broader bandwidth and more precise control in various applications.
3) Enhanced Power Density: WBG materials enable the design of more compact and lightweight electronic components. Meaning more power packed into a smaller space, ideal for size-constrained applications.
4) Enabling Alternate Topologies: Simple, elegant topologies which cannot be realized with silicon switches can often become reality using WBG devices. The bridgeless totem-pole power-factor-correction circuit is a prime example.

The choice between Si, SiC and GaN
Sales of EVs are growing rapidly, and the charging infrastructure is struggling to keep up in some regions. To meet customer demand for fast charging, we need at least six million new chargers by 2030, in the EU alone.
EV chargers need to deliver high power, with the efficiency and reliability to operate 24x7. A new technology area is vehicle-to-grid (V2G), where vehicles can return power to the grid – for example, to help meet peak demands – which again requires a reliable, efficient solution.
