High-frequency transformer and pulse transformer difference

First, the nature is different

1, high-frequency transformer: the working frequency exceeds the intermediate frequency (10kHz) of the power transformer.

2, pulse transformer: is a kind of broadband transformer.

Two, different uses

1, high frequency transformer: mainly used in high frequency switching power supply for high frequency switching power transformer, also used in high frequency inverter power supply and high frequency inverter welding machine for high frequency inverter power transformer.

2, pulse transformer: pulse transformer is widely used in radar, conversion technology; Matching of load resistance and characteristic impedance of the feeder; Increase or decrease pulse voltage; Change the polarity of the pulse; The isolation of the transformer's secondary and primary circuits uses several secondary windings to obtain the phase relationship.

Three, the principle is different

1, high-frequency transformer: in the design of high-frequency transformer, transformer leakage and distributed capacitance must be reduced to a minimum, because the high-frequency transformer in the switching power supply transmission is high-frequency pulse square wave signal. During the transient process of transmission, leakage and distributed capacitance can cause surge current and peak voltage, as well as top oscillation, resulting in increased losses.

2, pulse transformer: the use of the magnetic saturation performance of the core input sinusoidal voltage into a narrow pulse output voltage transformer.
