| Abstract |
Conventional linear current control with pulse width modulation and predictive current control for a three phase voltage source inverter are compared in this paper based on the ripple of current for a range of switching frequencies. Predictive current control allows to improve the performance by increasing the sampling frequency, but the resulting switching frequency can also make the semiconductors to operate out of their thermal limits. Behavior of the predictive control scheme for a range of switching frequencies is presented. A modification of the predictive current control is presented for decoupling the switching frequency from the sampling frequency, thus the performance of the system is improved and the switching frequency is kept controlled. |
