DC panel battery uninterrupted power supply switching circuit

The DC panel battery is commonly utilized in power plants and substations within DC systems. To enhance the safety and reliability of the current system, an uninterrupted power supply switching circuit may be implemented. This circuit includes components such as a thyristor, a voltage regulator, and a resistor. When the AC 380V power supply is functioning normally, the voltage regulator is off. However, if the AC 380V power supply is interrupted or if the motor's output voltage drops due to a fault, the voltage regulator activates, allowing the battery to supply power to the control bus immediately.

The described circuit functions as a critical component in maintaining an uninterrupted power supply in DC systems, particularly in environments where reliability is paramount, such as power plants and substations. The architecture typically includes a thyristor, which acts as a controlled rectifier, allowing for the regulation of power flow from the battery to the load. In normal operation, the thyristor remains off, preventing current flow.

The voltage regulator serves to stabilize the output voltage from the AC supply, ensuring that the load receives a consistent voltage level. In the event of an AC power interruption, the voltage regulator detects the drop in voltage and activates the thyristor. This action allows current from the battery to flow to the control bus, effectively bridging the gap during power outages.

A resistor is also integrated into the circuit, playing a vital role in limiting the current and protecting the components from overcurrent conditions. This resistor can be strategically placed to ensure that the system operates within safe parameters, thereby enhancing the overall reliability of the power supply.

In summary, this DC panel battery switching circuit is designed to seamlessly transition power sources, ensuring that critical systems remain operational during AC supply failures. The combination of a thyristor, voltage regulator, and current-limiting resistor creates a robust solution for maintaining power integrity in essential infrastructure.DC panel battery is widely used in power plants, substations DC system.
