Prediction of brushless DC drive performance considering non-sinusoidal parameter variations and asymmetrical operating conditions

Creator:

Spee, Rene

Abstract:

A highly flexible numerical simulation model for the performance prediction of brushless dc drives is presented, which is capable of investigating unbalanced and asymmetrical operating conditions as well as drives with non-ideal parameters. Numerical speed-up procedures allow for the investigation of pulse-width modulated (PWM) drives using a personal computer. Experimental...

CMOS analog design using a digital gate array

Creator:

Liu, Tian-chen

Abstract:

The core area of a conventional CMOS digital gate array consists of only one size of NMOS device and one size of PMOS device. Both primitives have fixed minimum channel lengths, and this has significantly impeded analog applications. This work has shown that by forming series and parallel interconnections between...
