| Abstract: | Seeing that it is rather difficult to detect the fundamental voltage output of voltage source inverter precisely and by real time,starting with DC supporting voltage,the author airs a new proposal to perform real time calculation of the transient fundamental voltage output by means of DSP according to an output pulse sequence of controller.The test results prove that the proposal is feasible. |
