In this article, a real- time system has been designed for protecting and monitoring DC/AC converter. This system consist of a hardware protection unit for fast reaction, load protection and inverter fail- safe operation and a micro controlling unit for calculating critical parameters of the inverter operation. This hardware architecture and sensors form a reliable, low -cost control unit. The experimental results show that this system can ensure the inverter protection and fail- safe features.
