Problems solved by technology

Although the existing dual power supply circuit has more functions, the circuit is complicated, there are many fault points, the manufacturing cost is high, and the maintenance is inconvenient
Moreover, most of the dual power supplies are often used at the end of the power supply system, and there is no need for so many complicated protection functions. Therefore, the use of full-featured dual power supplies in such occasions not only increases the number of failure points, but also causes resource and energy losses. waste

Description

technical field [0001] The invention relates to a power supply circuit, in particular to an end-type dual power supply automatic transfer switch control circuit. Background technique [0002] At present, in daily production and life, there are many occasions where electricity requirements are relatively strict, and uninterrupted power supply is often required. However, in reality, due to various reasons, the power supply system will encounter one or another failure, which will lead to the interruption of power supply, which will bring inconvenience to people's life and cause production losses. In this case, it is required to use two power supplies to supply power at the same time. When a problem occurs in one power supply, another power supply will take over this power supply to continue supplying power. This work is mainly automatically completed by the dual power supply automatic transfer switch. Although the existing dual power supply circuit has many functions, the circ...
