Hello, the settings for svpwm inverter control using simulink epwm modules are given in the pictures I shared. Normally, I can drive the 6 switches using only epwmas. When I set up epwma, the automatic epwmb was its inverse. In my new work, however, epwma and epwmb are not each other's inverse. Therefore, different inputs need to be provided to both. I activated wa and wb inputs and adjusted the epwmb shown in the picture, but it still automatically takes the inverse of epwma.
My questions are as follows: Why is it not considering the signal I send through epwmb? There should be a 180-degree phase difference between the signals in epwmb's and epwma's carrier signal. How can I achieve this? (or When producing the module epwm1 and epwm1b, does it already compare the timers by taking a 180-degree phase difference?)I would appreciate your assistance.
