Generally, high-frequency transformers(communication transformer, push-pull transformer, pulse transformer) are used in electrical appliances, why do we choose high-frequency transformers, through the following performance to understand you will know the advantages of high-frequency transformers.
1. Improve energy conversion efficiency, use the power supply of high-frequency transformers, because the power supply tube works in the instantaneous conduction-off state, that is, the state of on-off and non-stop conversion, so we call it "switching power supply". The loss is about 30% lower than that of traditional iron core transformers. Unfortunately, the failure rate is relatively high.
2. High-frequency pulses can be devoltageized, and ordinary transformer cores do not have ferrite cores and have high magnetic permeability. It can't be done
3. Improve the conversion efficiency, use the power supply of high-frequency transformer, because the power supply tube works in the instantaneous conduction-off state, that is, the state of non-stop conversion when it is turned on and off, so we call it "switching power supply". The loss is about 30% lower than that of traditional iron core transformers. Unfortunately, the failure rate is relatively high. What can be learned is the comparison between old-fashioned ballasts and electronic ballasts.
