Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc

Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality.

An old idea, the Class D amplifier has taken on new life as equipment manufacturers and consumers redefine the musical experience to be as likely to occur in a car, on a personal stereo, or on an airplane as in a living room. For most consumers today, portability and st ....etc
