Input voltage fluctuation
The power supply itself is unstable, and the input voltage is sometimes high and sometimes low, which affects the output voltage of the high-frequency transformer.
Load change
The connected load suddenly increases or decreases, exceeding the adjustment capacity of the transformer, resulting in output voltage fluctuations.
Core saturation
Improper selection of core material or excessive magnetic flux density during operation causes the core to enter a saturated state, affecting the electromagnetic conversion efficiency and resulting in unstable output voltage.
Winding failure
Short circuit, open circuit or poor contact in the winding affects the electromagnetic induction effect and causes abnormal output voltage.
Temperature change
The working environment temperature is too high or too low, which may cause changes in the magnetic conductivity of the core and the resistance of the winding, thereby affecting the output voltage.
High-frequency interference
The presence of strong high-frequency electromagnetic field interference in the surrounding area affects the normal operation of the transformer and causes unstable output voltage.
Irrational circuit parameter design
Parameters such as turns ratio and inductance are calculated incorrectly or inaccurately, resulting in the output voltage not meeting expectations and being unstable.
Failure of components such as capacitors or diodes
In the rectification and filtering circuits used with high-frequency transformers, capacitor leakage and diode damage will affect the stability of the output voltage.
Core material problem
Poor core quality, uneven magnetic permeability or unsatisfactory hysteresis loop affect the stable transmission of magnetic field.
