This article represents research on fault diagnosis of inverter electric drives. It puts more emphasis on power electronics and drives. The paper begins with the diagnostics of systems with conventional inverter drives, because knowledge of the fault diagnosis in conventional inverter can be used for its applications in other topologies of inverter drives. Therefore, the article describes several methods for troubleshooting.

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.
