abc to dq transformatioc
hi i am trying to implement a inverter control in dspic30F4011 controller. the problem is i am not able to develop a method to implement abc to dq transformation. since both are rotating reference frames an angle is required to synchronise the dq reference frame to abc reference frame. for this purose i have implemented a PLL that can determine the frequency from the grid. now i am not able to find a method to convert it into an angle so that i can give it for the abc- dq transformation. since it is an online operation the angle has to be determined continously and it has to be given to convert to dq frame. is there any way by which i can determine the angle from frequency obtained from the pll. or is there any hardware IC's available that can perform this abc to dq transformation.
