    Modern applications use complex controls to enhance safety, implement convenient features, and save energy. Control units use switches to control the sensors and actuators in a system. Since most applications are powered from the AC mains network, several AC voltage loads have to be controlled (For example, heaters, lamps, motors, fans or valves).

    SPICE is a powerful general purpose analog and mixed-signal circuit simulator that is used to verify circuit designs and to predict the circuit’s behavior. The original Spice program has given rise to a variety of commercial implementations. Among them is PSpice, a version for use on a PC which provides a comfortable graphic user interface. For this reason, PSpice has become very common and is widely used by engineers. An essential requirement for achieving quick and accurate simulation results is a well assembled library containing the circuit’s parts.
