Hi! I have a DC-DC Boost Converter with a transformer and 6 switches with high switching frequency at Fs=35KHz. Do these blocks for transformers support this operation in simullink as the results obtained show the output frequency of the secondary winding of the transformer to take the desired value simultaneously and afterwords to be decreased I guess due to losses. Do you know how the output voltage could remain in this value constant during the simulation time? Is there any other block for a transformer that could be used without any losses? Thanks a lot in advance!
