Description

technical field [0001] The invention relates to the field of electronics, in particular to an adjustable power supply for an aerator based on a thyristor overcurrent protection circuit. Background technique [0002] With the improvement of people's quality of life, more and more people like to raise goldfish at home, and the situation of insufficient oxygen supply in the fish tank usually occurs when raising goldfish indoors. Therefore, people usually adopt electromagnetic oscillation type aerator to increase oxygen for goldfish. Insufficient oxygen supply or excessive oxygen supply will harm the fish when using an aerator to increase oxygen for goldfish. When using an aerator to increase oxygen for goldfish, it is necessary to ensure the stability of the amount of oxygen in the fish tank, and the oxygen supply of the aerator Whether it is stable depends on whether the electromagnetic oscillation frequency of the aerator is stable. However, the existing power supply for ae...
