Solar inverter Hall

How do EV charging and solar inverter systems work?

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.

Can a Hall-effect sensor be used in a high-voltage system?

These high-voltage systems use current flow information to control and monitor power conversion, charging and discharging. Hall-effect and shunt-based current sensors are among the most common technologies requiring current sensing. However, to date, using Hall-effect sensors in high-voltage applications has been problematic.

What is a Hall effect current sensor?

Hall-effect current sensors enable current measurements for rails as high as 1,100 V, with reinforced isolation to ensure the safety of other system electronics. Industry leading temperature drift of ±50PPM/C, and ±0.5% of lifetime drift. Support for up to ±1,100-V working voltage. Supports both AC and DC monitoring.

Why do we need high-efficiency power inverters?

The advent of the Smart Grid, Plug-in Hybrid Electric Vehicles (PHEV), and full Battery Electric Vehicles (BEV), as well as grid-tied photovoltaic (PV) and other grid-tied renewable energy systems, requires development of high-efficiency power inverters. Usually, higher efficiency is associated with higher application cost and reduced performance.
