Abstract

The invention discloses an offset adjustment current circuit-based adjustable power supply for an over-current protection aerator. The adjustable power supply is characterized by mainly comprising a control chip U2, a transformer T, a diode rectifier U1, a polar capacitor C1, a polar capacitor C2, a polar capacitor C6, a resistor R12, a diode D6, a polar capacitor C8, a voltage detection circuit, a voltage-controlled oscillation circuit, a thyristor overcurrent protection circuit and an offset adjustment current circuit. By the offset adjustment current circuit-based adjustable power supply, leakage current and loss current of input current can be effectively reduced, abnormal fluctuation of the input current can be inhibited and the input current is kept stable. Furthermore, the current intensity of output current can also be adjusted, so that the stability of output voltage and current is ensured and the stability of the electromagnetic oscillation frequency of the aerator is effectively ensured.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an adjustable power supply for an overcurrent protection type aerator based on an offset adjustment current 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 existi...
