Abstract	A multidisciplinary design optimization (MDO) was performed for a rectifier, which is one of key components of uninterruptible power supplies (UPS), using AI-Aided Design Optimization (AADO) technology. First, the design variables and performance indices of the target rectifier were clearly defined to formulate a MDO problem. Then, a multidisciplinary analysis procedure was established using commercial simulation software. Through AADO technology, optimal circuit design variables and heatsink shape parameters were successfully determined, achieving a 36.1% reduction in heatsink volume while satisfying various constraints on circuit performance and temperature.
