Highly Efficient 3-Level solutions for renewable energy applications. issue 5/2010 September, 01 2010
Energy efficency is one of the major criteria for photovoltaic (PV) and wind power inverters. The 3-level inverter topology proves to be one of the most attractive candidates for low and medium power, low voltage applications which require high switching frequencies, complex filtering and high efficiency. The same advantages can be seen for Uninterruptible Power Supplies (UPS) which are connected and loaded 27/7.....

Shunt Current Measuring up to 800A in the Inverter October, 19 2009
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.
