| Abstract: | Based on the principle of selected harmonic elimination(SHE),a math model of generating harmonic was founded,and the relations between the switch point and each times of harmonic were studied.The conclusion that the real-time calculate is more suitable than the check-table method when generate harmonic is gained.The hardware and software for real-time control of the SHE inverter were designed,and two examples of experiment result were analyzed. |
