I have been simulating a high frequency transformer isolated micro--inverter. Currently I am using a LINEAR TRANSFORMER model from Simulink library(I have edited the frequency, power,turns ratio and Lm),but I am facing issues with power balance.My switching frequency is 20 khz.Looking for different good answers?

Design factor of high frequency transformers
Yes. your observations are right. i also faced same issues. for systems where high frequency transformer model is required, MATLAB Simulink fails because in MATLAB model by default, it assumes 2% losses and when we use our parameters of Lm Rm, L1, L2, R1 and R2, power balancing becomes the real problem.
I suggest you to use PSIM which also takes coupling coefficients into consideration. Design your high frequency transformer using other software like HFSS or ANSYS Maxwell, extract your parameters from it and use them in PSIM.
