Abstract

Systems, apparatuses, and methods are described for melting snow from a surface of a power source. The power source may be a photovoltaic (PV) module.

Claims (42)

1. An apparatus comprising:

first terminals configured to interface with a power source;

second terminals configured to interface with a plurality of power devices; and

circuitry configured to:

in a power conversion mode of operation, convert voltage from the first terminals to the second terminals; and

in a heating mode of operation, convert voltage from the second terminals to the first terminals;

wherein the circuitry comprises a heating element configured to be in thermal proximity to a surface of the power source, and the heating element comprises a body diode.

2. The apparatus of claim 1 , wherein, in the power conversion mode of operation, the circuitry is further configured to decrease higher voltage at the first terminals to lower voltage at the second terminals.

3. The apparatus of claim 2 , wherein, in the power conversion mode of operation, the circuitry is further configured to convert current from the first terminals to the second terminals.

4. The apparatus of claim 1 , wherein, in the heating mode of operation, the circuitry is further configured to increase lower voltage at the second terminals to higher voltage at the first terminals.

5. The apparatus of claim 4 , wherein, in the heating mode of operation, the circuitry is further configured to convert current from the second terminals to the first terminals.

6. The apparatus of claim 1 , wherein the circuitry comprises buck converter circuitry configured to step down voltage from the first terminals to the second terminals.

7. The apparatus of claim 1 , wherein the circuitry comprises boost converter circuitry configured to step up voltage from the second terminals to the first terminals.

8. The apparatus of claim 1 , wherein the heating element is a part of converter circuitry.

9. The apparatus of claim 1 , wherein, in the heating mode of operation, the second terminals are configured to receive power from an external power source.

10. The apparatus of claim 9 , wherein the external power source comprises an electrical grid.

11. The apparatus of claim 9 , wherein the external power source comprises a second plurality of power devices connected to the plurality of power devices.

12. The apparatus of claim 11 , wherein the second plurality of power devices is connected in parallel to the plurality of power devices.

13. The apparatus of claim 11 , wherein each power device of the second plurality of power devices is connected to a respective power source of a plurality of power sources.

14. The apparatus of claim 13 , wherein the plurality of power sources are photovoltaic (PV) modules.

15. The apparatus of claim 1 , wherein the power source is comprises a photovoltaic (PV) module.

16. The apparatus of claim 1 , wherein the circuitry is configured to:

in a first mode of operation, transfer power from the first terminals to the second terminals; and

in a second mode of operation, transfer power from the second terminals to the first terminals.

17. A system comprising:

a plurality of power sources;

a plurality of power devices, each of the plurality of power devices comprising:

first terminals configured to interface with a respective power source of the plurality of power sources, and

second terminals configured to interface with the plurality of power devices; and circuitry configured to:

in a power conversion mode of operation, convert voltage from the first terminals to the second terminals; and

in a heating mode of operation, convert voltage from the second terminals to the first terminals;

wherein the circuitry comprises a heating element configured to be in thermal proximity to a surface of the respective power source, and the heating element comprises a body diode.

18. The system of claim 17 , wherein the circuitry is configured to:

in a first mode of operation, transfer power from the first terminals to the second terminals; and

in a second mode of operation, transfer power from the second terminals to the first terminals.

19. A method comprising:

converting, based on a power conversion operation mode of circuitry, voltage from first terminals of the circuitry to second terminals of the circuitry, wherein the first terminals are configured to interface with a power source and the second terminals are configured to interface with a plurality of power devices; and

converting, based on a heating operation mode of the circuitry, voltage from the second terminals of the circuitry to the first terminals of the circuitry;

wherein the circuitry comprises a heating element configured to be in thermal proximity to a surface of the power source, and the heating element comprises a body diode.

20. The method of claim 19 , wherein the circuitry is configured to:

transfer power from the first terminals to the second terminals in the power conversion operation mode; and

transfer power from the second terminals to the first terminals in the heating operation mode.
