Delivering accurate current sensing for safer solar energy systems and EV chargers
Our society relies on the electric grid every day, so monitoring and maintaining the grid is vital in order to ensure day-to-day reliability. The everyday supply and demand from the grid is changing as more people transition from non-renewable to renewable energy sources, so we must manage its evolving needs.
Why accurate and reliable high-voltage sensing is critical to the future of electrification
Today’s high-voltage systems — such as electric vehicles (EVs), energy storage systems and distributed solar energy applications — are equipped with many modern sensors. These sensors are able to sense the world around them more accurately, quickly and reliably, playing a crucial role in helping speed up the adoption of renewable energy sources.
Simplifying high-voltage sensing with Hall-effect current sensors
In electric vehicle (EV) charging and solar inverter systems, current sensors measure current flow by monitoring the voltage drop across a shunt resistor or the magnetic fields generated by current flowing through a conductor. These high-voltage systems use current flow information to control and monitor power conversion, charging and discharging.
How precision ADCs enable highly accurate metering systems in EV chargers
The electric vehicle (EV) charging industry is experiencing rapid growth. With consumers, industries and governments demanding more environmentally sustainable transportation, the EV charging infrastructure must become more efficient and accessible.
