常见问题

What is the typical efficiency range for automotive receiving coils?

Modern automotive receiving coils achieve 90-95% efficiency in optimal alignment conditions, with system efficiency typically 85-92% including power electronics.

How does alignment affect receiving coil performance?

Misalignment reduces coupling coefficient and efficiency. Modern systems maintain >85% efficiency within ±75mm lateral offset through optimized coil design and control algorithms.

What materials are critical for high-frequency performance?

Litz wire minimizes skin effect losses at high frequencies, while Mn-Zn ferrite cores provide high permeability and low core losses at 85-205 kHz operating ranges.
