چکیده

pulse-width modulated (pwm) adjustable frequency drives (afds) are extensively used in industries for control of induction motors. it has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. they increase voltage and thermal stresses; resulting into accelerated insulation aging. this paper presents the application of fuzzy logic to life estimation of pwm driven induction motors. insulation stress parameters are experimentally computed for wide range of switching frequency and used in fuzzy logic based life estimation algorithms. the results obtained with the fuzzy expert system show a performance approaching that attainable for the life model based on the inverse power law.

Hybrid Resonant Inverter Fed Induction Heating Using Fuzzy Logic Based PWM

The inverters are commonly used for medium power induction heating applications. In the process of induction cooking, a disc of metal is surrounded by a copper coil through which an alternating current is made to flow. The disc has a finite diameter and thickness. It is placed at a given distance from the coil and concentric to it. Secondary current is induced in the disc and this induced curre...
