Hi guys, in this video JRPanel would like to introduce you the design principle of HIgh Frequency Transformer. When designing a high frequency transformer, the leakage inductance and distributed capacitance of the transformer must be minimized. The reason is that the high-frequency transformer in the switching power supply transmits a high-frequency pulse square wave signal. During transmission transients, leakage inductance and distributed capacitance cause inrush current and peak voltage, as well as top oscillation, resulting in increased losses. Usually we control the leakage inductance of the transformer to be 1% to 3% of the primary inductance.
