LATEST FEATURE: Shunt Current Measuring up to 800A in the Inverter Read PDF
In 2005, Siemens Drive Technologies introduced the first large inverter using shunts for phase current measuring and brought it into series production. It wasn’t until recently that the power output was extended to 132kW with the new inverter SINAMICS G120 series. Back then, the joint development between Siemens, Semikron and Isabellenhütte laid the foundations for being able to measure currents of up to 800A today. This article looks back at past events and takes a glimpse into the future.
