Abstract

In aeronautical systems, the system traditionally operates with fixed frequency (400 Hz). In the More Eletric Aircraft concept, the airplanes operate with a variable frequency (360 Hz to 800 Hz), and due to increased power demand, the systems tend to use high voltage de buses (+/- 270 V). This paper analyzes the 12-pulse passive rectifier to meet those specifications and the aeronautical standards with fixed frequency. Two sorts of input filter were evaluated: L and LC. A mathematical model that includes the harmonic components of the system is developed and allows to analyze the input current and the output voltage. Simulations and a prototype were developed to validate the model. (AU)
