1Power
If multiple generators are connected in parallel to supply power to commercial vehicles, then the power supply capacity is increased, but the output power becomes non-homogeneous and voltage fluctuations occur
Solution Approach 1:
A current bridge is introduced as an intermediary component between the generators and the consumer circuits. This current bridge actively monitors and regulates current distribution, ensuring homogeneous power output from parallel generators while maintaining increased power supply capacity. The current bridge acts as a mediator that balances the electrical output among multiple generators.
Solution Approach 2:
The system dynamically adjusts electrical parameters (current distribution, voltage regulation) through the current bridge to maintain homogeneous output. By changing operational parameters in real-time based on generator performance, the system achieves stable combined output from parallel generators despite individual variations.
2Ease of manufacture
If standard power connections are used between generators and consumers, then the system is simple to implement, but voltage fluctuations and non-homogeneous power supply occur
Solution Approach 1:
The current bridge serves as an intermediary that maintains simple system architecture while improving voltage stability. It integrates into the existing parallel generator configuration without requiring complete system redesign, thus preserving ease of implementation while actively stabilizing voltage and ensuring homogeneous power distribution.
Solution Approach 2:
The current bridge incorporates feedback mechanisms that continuously monitor generator output and consumer demand, automatically adjusting current distribution to maintain stable voltage. This closed-loop control ensures reliability without adding significant system complexity.
