Abstract

The invention discloses a multi-output multi-purpose power supply circuit capable of being fully charged, which comprises a mains supply, a step-down rectification filtering module, a switch module, an adjustable voltage stabilization module, a square wave output module, an oscillation starting module and a multi-power supply output module, and is characterized in that the mains supply is connected with the step-down rectification filtering module, the step-down rectification filtering module is connected with the switch module, the switch module is connected with the adjustable voltage stabilization module, the adjustable voltage stabilization module is connected with the square wave output module and the oscillation starting module, the square wave output module is connected with the oscillation starting module, and the oscillation starting module is connected with the multi-power output module. The multi-output multi-purpose power supply circuit possesses beneficial effects that the multi-output multi-purpose power supply circuit can output a plurality of voltages for electric equipment to use, when it is needed to charge a battery, the potentiometer resistance value can be adjusted to change the duty ratio of square waves output by a 555 timer, so that when the battery is charged, the battery can release charges accumulated on the positive electrode of the battery, the charging effect is ensured, and the battery can be charged to a rated voltage.

Description

technical field [0001] The invention relates to a power supply circuit, in particular to a multi-output and fully chargeable multi-purpose power supply circuit. Background technique [0002] At the end of the 19th century, Thomas Edison successfully used direct current transmission to light up light bulbs, but the efficiency of direct current transmission was very low because of the huge energy loss. Later, Nikolates invented AC transmission, which replaced DC transmission. In the case of AC transmission, the voltage can be easily stepped up or down through a transformer, and the power can be transmitted over long distances. Today, AC transmission is commonly used in countries all over the world, albeit with varying voltages and frequencies. The power supply frequency is 50Hz or 60Hz, and the power supply voltage is 100V to 240V. Vacuum tubes and radio receivers were invented at the same time that alternating current appeared, but they needed direct current to work, so a ...
