This paper describes a nondestruct tester for measuring and verifying the FBSOA limits of power MOSFETs. Because the tester is nondestructive, an entire curve can be plotted with one transistor. Device trends thus become apparent and clues to failure mechanisms can sometimes be obtained. On a standard log-log plot, the curve usually describes a straight line with a slope slightly steeper than the...
Sliding mode control is an effective means to keep a system insensitive to parametric variations and disturbances. In the conventional sliding mode control applied to position servo systems, the sliding mode regime is restricted near the origin, and therefore insensitivity cannot be ensured throughout an entire response. This paper presents a new method in which a sliding curve is used instead of...
