Power converters with carrier based pulsewidth modulation (PWM) are currently the most widespread solution in industrial drive applications. However, the average dead time of the current controller affect the transient behavior of the whole drive. Therefore hysteresis and predictive current control can be seen as an alternative to PWM, providing enhanced transient response with the major drawback...
The common trend in converter development is to increase the drive system performance with simultaneous consideration of cost reduction by operating the whole drive at its thermal limit. For this purpose all system components are, for short durations, even stressed above their rated values. Because thermal losses have to be well balanced it is necessary to adjust inverter switching frequency to its...
