Resumen

In order to improve the performance at steady state of a three-phase drive system, numerous works have been focused in reducing the current and torque ripple. Predictive current control allows the improvement of the performance by increasing the sampling frequency, but the resulting switching frequency can generate semiconductors operating point out of their thermal limits. The ripple of current using conventional linear current control with pulse width modulation is reduced by increasing the carrier frequency, however, the upper limit of the switching frequency is limited also by the semiconductors thermal rates. In this paper a predictive current control modification is proposed for reducing the switching frequency by decoupling it from the sampling time, thus the performance of the system is improved but the switching frequency is kept bellow its limits. A comparison between the proposed method and linear current control with PWM of a three phase voltage source inverter operating at steady state is presented.
