| Optimizing design of converters using power cycling lifetime models | ||||||
| Author(s) | Rasmus Ørndrup NIELSEN | |||||
| Abstract | Converter power cycling lifetime depends heavily on converter operation point. A lifetime model of a single power module switched mode power supply with wide input voltage range is shown. A lifetime model is created using a power loss model, a thermal model and a model for power cycling capability with a given mission profile. A method to improve the expected lifetime of the converter is presented, taking into account switching frequency, input voltage and transformer turns ratio. | |||||
