Main Advantages of 3-level Inverters

Posted on 16 April 2020

  3-level inverters can be used in many applications, notably UPS and solar inverters. The main advantages of 3- level inverters are: Smaller output voltage steps that mitigate motor issues due to long power cables between the inverter and the motor Improvement of spectral performance Reduction of size and filter of the inverter Increasing of switching frequency [...]

Compact Inverters

Posted on 18 July 2020

  Off-the-shelf, powerful traction-drive inverters with motor-control software are an ideal solution for electrical powertrains. Hybrid and electrical powertrains have become the trend. Fossil fuel shortages are on the horizon and the global call for climate protection is motivating manufacturers and suppliers to promote the development of powertrains that are future-oriented while being powerful and [...]

More Efficiency for 3-Level Inverters

Posted on 31 March 2020

  The use of renewable energy sources is one of the key issues when it comes to creating a new basis for worldwide energy supply. Wind power has been in use for over 20 years now, with technical advances leading to improvements in efficiency and reliability. The output of wind power units is steadily increasing. [...]

Shunt Current Measuring up to 800A in an Inverter

Posted on 01 November 2020

  Shunt Current Measuring up to 800A in an Inverter 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 [...]

Modular and Powerful Inverters up to 1MW

Posted on 01 December 2020

  Over the last few years, the call for a faster time-to-market for industrial products has become increasingly urgent, causing developers to combine existing subsystems to create a final product. The main aim in doing so is to save time and money in the development stage. To meet the increasing demand for qualified, tried and [...]

Plug and Play IGBT Driver Cores for Converters

Posted on 06 March 2020

              The key component of every power electronic system is – besides the power modules themselves – the IGBT driver which forms the vital interface between the power transistor and the controller. For this reason, the choice of driver is closely linked with the degree of reliability of a [...]

Modular Inverters for High Power Applications

Posted on 20 November 2020

  High power configurations to offer ratings from 320 to 1550A Modular power systems must offer user benefits in terms of shorter lead times and lower costs. The modular SEMIKUBE B6CI is a compact, easy to maintain and flexible system for forced air-cooled inverters from 300A up to 1550A. Built around the latest IGBT technology [...]

Packaging considerations of an Integrated Inverter Module (IIM) for Hybrid Vehicles

Posted on 02 July 2020

  New fields of high power inverter systems such as hybrid cars, hybrid trucks, and off road vehicles require new ways of power electronics integration and packaging. The stringent requirements in size and weight, reliability, durability, ambient temperature, and environment can be fulfilled by a careful consideration of IGBT and Diode chip selection, novel packaging [...]
