Magnetic Core Switching Power Supply High Frequency High Voltage Transformer EE25

Magnetic core switching power supply high-frequency transformer EE25

Design principle of high frequency transformer
In the design of high-frequency transformer, the leakage inductance and distributed capacitance of transformer must be reduced to the minimum, because the high-frequency transformer in switching power supply transmits high-frequency pulse square wave signal. In the transient process of transmission, leakage inductance and distributed capacitance will cause surge current, spike voltage and top oscillation, resulting in increased loss. Generally, the leakage inductance of the transformer is controlled to 1% ~ 3% of the primary inductance.

The leakage of primary coil ---- the leakage of transformer is caused by the lack of complete coupling of magnetic flux between primary coil and secondary coil, between layers and between turns.
