Secondly, the high-frequency pulse transformer in the case of high-voltage, high-current, two-way frequency rectangular pulses reach several tens of kHz, the iron core is rapidly repeatedly magnetized, the iron loss inevitably large, and the frequency increases, the same flux density Bm Under the conditions, the iron loss will increase, but will cause the core temperature rises, and the temperature rise and cause a decline in saturation induction BS. Therefore, the operating frequency of the inverter transformer is determined to be a reasonable choice of parameters according to the iron core loss. Since the original high-frequency transformer, fewer by turns, the copper loss is generally small. But accurate calculation Pcu very complex and usually is given by all winding copper loss: Pcu = J2KwcuLAc (9) where cu is the resistivity of copper winding material, L is the average length of the core window. When both losses ratio Pco / Pcu = 2 / n, ie the best copper, iron loss ratio, can be made to minimize the loss of the entire transformer. Therefore, after the design of high-frequency transformer, the core material is selected and the inverter frequency f, minimum power consumption from the viewpoint of optimal selection operating flux density B and winding current density J.
