High-Fidelity IEC 61851 Pilot Line Decoding
Real-time sampling of the 1 kHz PWM pilot signal and HomePlug Green PHY powerline communication carrier with active noise cancellation.
Carrier Noise Suppression
Digital filtering mitigates switching noise from adjacent 800V traction inverters during combined charging and pre-conditioning.
- PWM duty cycle measurement accurate to 0.1%.
- Sniffer attenuation compensation across CCS cables.
- Instantaneous detection of pilot wire severance in under 100 µs.
- Isolated capacitive barrier exceeding 4 kV breakdown rating.
