Functional safety in power electronics converters

摘要

Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people, named Functional Safety, has been gaining importance. The paper presents the basics of the design process to be applied for the development of electrical / electronic / programmable electronic devices to be applied in safety critical applications.
