Modern power conversion systems must simultaneously become more efficient, smaller and cheaper than the previous generation. With this in mind, LEM, the global leader in current and voltage sensing, has used its industrial expertise to create a single chip package: the HMSR current sensor.
LEM expands its miniature, integrated circuit transducers range for AC and DC isolated current measurement up to 300 KHz with the introduction of the GO series
New technologies allow photo-voltaic (PV) inverters to switch at ever higher frequencies and consequently they are becoming much smaller and lighter. International competition and the move away from subsidies for new installations mean that there is strong pressure on their cost.
