When the PLC device is directly coupled to a high-voltage PLC network, the PLC device can comprise printed safety capacitors in series with a high-voltage input AC powerline signal to safely couple the high-voltage AC powerline signal to the low-voltage processing circuit. The PLC device can also comprise an ADC to sample a scaled AC powerline signal and to obtain zero cross information. When the PLC device is part of an embedded PLC application, dynamic loading can affect the integrity of a low voltage zero cross signal that is used to extract zero cross information. After digitizing the zero cross signal, the PLC device can execute functionality to minimize/eliminate voltage drops caused by dynamic loading and obtain the zero cross information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extracting zero cross information in a powerline communication device","description":"A powerline communication (PLC) device can be configured to execute functionality for zero cross sampling and detection.
