At present on the Utilized Energy Electronics Convention (APEC), Infineon Applied sciences AG launched a brand new product household of Strong-State Isolators (iSSI) to attain quicker and
extra dependable circuit switching with safety options not accessible in optical-based stable
state relays (SSR). iSSI use coreless transformer know-how and assist 20 occasions larger
vitality switch with each present and temperature safety contributing to a better
reliability and decrease price of possession. The brand new iSSI enable driving the gates of Infineon’s
MOS-controlled energy transistors OptiMOSTM and CoolMOSTM to scale back energy dissipation
of as much as 70 % of todays’ solid-state relays utilizing SCR (silicon-controlled rectifier) and
Triac switches.

Infineon’s solid-state isolators allow customized solid-state relays able to controlling masses
greater than 1000 V and 100 A. Improved efficiency and reliability make coreless
transformer know-how very best for functions in superior battery administration, vitality
storage, renewable vitality methods, in addition to industrial and constructing automation system
functions. With iSSI drivers, engineers can additional enhance the effectivity of digital
and electromechanical methods.

“Implementing coreless transformers in solid-state isolators and relays is actually a game-
changer for energy engineers; it supplies 50 occasions decrease RDS(on) than current optically managed options. This allows their use in higher-voltage and better energy functions,” mentioned Davide Giacomini, Advertising Director for the Inexperienced Industrial Energy
Division at Infineon Applied sciences.

When matched with Infineon’s CoolMOS S7 change, the iSSI drivers allow switching
designs with a a lot decrease resistance in comparison with optically pushed solid-state options.
This interprets to longer lifespans and decrease price of possession in system designs. As with
all solid-state isolators, the units additionally provide superior efficiency in comparison with
electromagnetic relays, together with 40 % decrease turn-on energy and elevated reliability
as a consequence of elimination of transferring elements.

The household of units is designed to be appropriate with Infineon’s broad switching portfolio
together with Infineon’s CoolMOS S7, OptiMOSTM and linear FET portfolios.
