transformers operate at 50 or 60 Hz, high-frequency transformers use frequencies from 20 KHz to over 1MHz. Operating at a higher frequency has many benefits, the first of which is size. For any given power rating, the higher the frequency, the smaller the transformer can be. Second, because the transformer is smaller, less
Transformer size is thus determined, not only by the load demand, but also by current wave shape. An example of the primary and secondary, VA, will be done to compare the power-handling capability required by each three-phase rectifier circuit in Table 12-1 and Figures 12-1 1 through 12-14. This comparison will negate transformer and diode ...
