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 of variable inverter switchingfrequency.
In this paper a novel predictive current
controller is proposed, using a penal weight in switching
state selection for controlling the switching-frequency.
Consequently inverter switching-frequency will no longer
dependent on current controller sampling time facilitating
sampling frequency to be increased up to some 100kHz at
an inverter switching-frequency of just a few kHz. Hence -
compared to classical predictive current control - a further
reduction of the transient response time can be
accomplished.
