Variable frequency drive operation to avoid overheating |
摘要 |
Operation of a variable frequency in a manner configured to avoid overheating is provided. In one form, a method includes providing a variable frequency drive that includes a switching device in thermal communication with a heat sink including a thermal mass. The method further includes operating the drive in a first mode before active cooling of the heat sink is established and a second mode following the first mode. Operation of the drive in the first mode includes operating the switching device in a first switching frequency mode, and the first switching frequency mode and the thermal mass of the heat sink are selected to provide a temperature of the switching device below a predetermined threshold before active cooling of the heat sink is established. Further embodiments, forms, features, and aspects shall become apparent from the description and drawings. |
