In order to verify the simulation situation, it is necessary to convert part of the simulation code. For the inverter to yield the corresponding duty cycle is controlled generally in two ways: 1. By calculating formula sin, real-time calculation of the output value, into epwm generator. Which divided into two kinds, one is directly calculated in this way in a simple situation can be used, but considering the amount of computation of DSP is relatively large, generally not used. Another is to use IQmaths function library functions provided by TI, can greatly reduce the computation time. 2. Offline reading table method. Experiments found that, if the call IQMATH direct calculation requires 60us. Since the switching frequency is 10K, the entire time-controlled limited to less than 100us. Direct meter reading, the time within 10us. If you want to add closed-loop control to get better results, must give way to off-line reading table.
