Imagine a Future Where Charging is as Fast as Refueling: The Role of Power Semiconductors in EV Charging
Think about this: What if charging an EV took just 10 minutes? No more long waiting times, no more range anxiety—just seamless, intelligent power distribution.
At Pingalax, this future is not a dream—it’s happening now. Powered by AI-driven technology and proprietary semiconductor innovations, we are redefining the way EVs charge by making power distribution faster, smarter, and more efficient.
1. Transition from Silicon to Wide-Bandgap Semiconductors
Traditionally, silicon-based power semiconductors dominated the EV charging industry. However, as charging power levels increased beyond 150kW, silicon-based transistors’ power loss and thermal inefficiencies became a bottleneck. Wide-bandgap semiconductors, particularly SiC (Silicon Carbide) MOSFETs and GaN (Gallium Nitride) transistors, have been integrated into high-performance EV chargers to overcome these limitations.
Key advantages of SiC MOSFETs over traditional silicon power devices include:
✔ Higher efficiency – Lower conduction and switching losses reduce energy waste.
✔ Faster switching speeds – Enables higher frequency operation, reducing charger size and weight.
✔ Lower heat dissipation – Less reliance on bulky cooling mechanisms, improving overall system longevity.
✔ Higher voltage handling – Critical for ultra-fast charging applications, up to 800V-1000V architectures.
