Abstract :
Today, static relays must be robust to withstand the a.c. line transients and to allow systems to be
compliant with new european ElectroMagnetic Compatibility (EMC) standards. ACSs (for Alternative
Current Switches) have been designed in this goal, i.e. to offer more robust semiconductor devices. In
other hand, ACSs have been developed in a functional integration approach. They can be used directly
between a micro-controller and the load. No external protection or buffer circuit are needed. This
reduce considerably the overall electronic board size.
