When the mains supply is connected, the circuit will draw power from the mains supply. When the battery supply is connected, the circuit will draw power from the battery supply. A dual power supply circuit is a great option for applications that require two power sources. It simplifies the design of the circuit and allows for greater flexibility.
The two power sources can be of different voltages, allowing for greater flexibility in the design of the circuit. This type of circuit is typically used in applications where it is necessary to draw power from both mains power and battery power simultaneously.
Connect the components as shown in the dual power supply circuit diagram. Make sure to follow the diagram exactly, and double-check your connections. 3. Connect the two power supplies to the circuit. The mains supply should be connected to the voltage regulator and the battery supply should be connected to the full-wave rectifier. 4.
The main benefit of a dual power supply circuit is the flexibility it provides. The ability to draw power from two distinct sources allows the circuit to be designed to best suit the needs of the application.
However, this does no harm, and there isn't really deliberate switching going on. The diodes are performing a MAX function on the two source voltages. Schottky diodes are fast, and can easily keep up with a battery and a power supply.
The final power output of this automatic switching circuits will be used to power 12v devices (30 Ampere maximum). It is important that the circuit provides uninterruptible power during switching and that it works in 11-14v range. P.S.: please provide a detailed list of the scheme and electrical components to be used. @Arsenal Why not?
