| Title | Dynamic Discontinuous PWM for Motor Drive Systems |
| Summary | Discontinuous pulse-width modulation (DPWM) consists of clamping the reference signal of one phase of a power converter during some intervals so that the corresponding phase-leg does not switch. Hence, DPWM helps to reduce switching losses in power converters. The objective of this project is to design a DPWM strategy where the clamping intervals track the peak of the absolute value of the currents, which will help to achieve a further power loss reduction. The clamping of the reference signals is performed by adding a zero-sequence voltage to the reference signals. The effect on the leakage current through the bearings of the motor due to the zero-sequence voltage will also be studied in this project. |
