Littelfuse unveiling SiC Schottky diodes at PCIM Europe

In booth 7-140 (Hall 7) at PCIM (Power Conversion Intelligent Motion) Europe 2016 in Nuremberg, Germany (10-12 May), Littelfuse Inc of Chicago, IL, USA (which provides circuit protection technologies) is unveiling two new power semiconductor families: the new LFUSCD Series of silicon carbide (SiC) Schottky diodes and its own silicon insulated-gate bipolar transistor (IGBT) technology.

"We are continuing to invest and develop our portfolio to bring interesting capability to the [power semiconductor] market," says Ian Highly, senior VP & general manager, semiconductor products, and chief technology officer at Littelfuse. "Littelfuse has the unique ability to combine typical portions of a power electronics system – protection, control, sense - into an integrated systems-level approach. No other technology supplier can bring the same level of coordination and integration of key elements of a power system," he claims.

An in-booth demonstration will illustrate the SiC MOSFET technology capabilities of supplier Monolith Semiconductor Inc of Round Rock, TX, USA, with a 5kW buck converter with 675V nominal input and 350V nominal output. The converter switches at high frequencies (~200kHz) with an efficiency (>98%) that cannot be achieved with silicon IGBTs.

In 2015, Monolith formed a strategic partnership with Littelfuse to develop SiC power semiconductors for industrial and automotive markets. Monolith's SiC MOSFET technology is said to enable drastic reductions in system size and weight (as a result of the higher-frequency capabilities) and power consumption (due to reduced power losses) across a broad range of applications in industrial and automotive markets. Representatives from Monolith and the designer of the power converter will be on hand at PCIM Europe to share additional information on Monolith's SiC technology.

The Littelfuse booth will showcase solutions for the following market applications:

• datacom power – protecting the global telecom network, from smart phones to cellular base-stations;
• solar – high reliability and safeguards for equipment and systems subject to harsh environments in photovoltaic installations;
• industrial drives – ensuring the safe control and distribution of electrical power in industrial applications; and
• electric vehicles (EV) & hybrid electric vehicles (HEV) – protect and control solutions for synchronizing, frequency control, load sharing and power management.
