Coverting from abc  waveform to qd0, I know I have to take the abc form and multiply by Ks matrix, which I have done bellow. However I am not sure how my answer is suppose to go from my calculation to the last set of 3 equation on the picture from 3.6-5 -3.6-7.

Power in Extreme Frequency Limits. You and your team have been assigned to find a power supply for the circuit in the drawing. which can be used to supply a dc voltage at 15.0 V, or a high frequency ac signal with a root-mean-square (rms) voltage of 15.0 V. The components in the circuit have the following values: R=4.600, C= 20 nF, and L = 22 mH. Your task is to estimate the peak wattage (i.e.. power) required of the power supply for (a) the dc and (b) the high frequency signals. Conceptual Example 5 will provide insight into this problem. (a) Number (b) Number 24.4 196 R ww Units W Units W C HH elle L R
