Abstract

See full text

Temperature value determination of at least one variable frequency drive component is provided. In one form, a method includes providing a variable frequency drive that includes a first component in thermal communication with a second component in thermal communication with a switching device. A temperature value of the second component is determined using a temperature value of the first component, a power loss characteristic of the drive, and a first characteristic of heat transfer between the first and second components. The method further includes sensing a temperature value of the second component and determining a temperature value for the switching device using the power loss characteristic, a second characteristic of heat transfer between the second component and the switching device, and the greater of the sensed and determined temperature values of the second component. Further embodiments, forms, features, and aspects shall become apparent from the description and drawings.
