Description:
Multiple Input Single Output DC-DC Converter with Equal Load Sharing on the Multiple Inputs
Need:
In a typical DC to DC power converter with multiple DC power sources the DC power converter circuit switches from one DC power source to another DC power source among the multiple DC power sources. However, the energy drawn from each of the multiple DC power sources can vary greatly due to the load on the DC power converter circuit when the corresponding one of the multiple DC power sources is being utilized. There is still an unmet need for a DC to DC converter that can draw energy from multiple inputs and effectively channel it into one output.
Solution:
A researcher at Cal Poly, San Luis Obispo has developed a multiple input single output DC-DC converter with equal load sharing on the multiple inputs. Specifically, a system, method and apparatus of balancing a direct current load across a multiple direct current power sources. The output current of each one of the direct current inputs is compared to a reference current. The direct current inputs are adjusted in corresponding DC to DC converter modules until the output current of each one of the direct current inputs is equal to the reference current. The adjusted output of the DC to DC converter modules is combined to a single output current that can be output to supply the single output current to a load.
Applications:
- Automotive Applications
- Aircraft Applications
- Charging Batteries
Advantages:
- Multiple methods for implementation
- Scalable
- Multiple power sources to supply single load
- Uses direct current instead of AC
