SOLAR SYNCHRONIZED LOADS FOR PHOTOVOLTAIC SYSTEMS

摘要

An electrical power supply arrangement includes a solar power device that converts sunlight into DC electrical power. A DC load runs on the DC current electrical power. The DC load may be controlled or adjusted to consume a maximum amount of the electrical output of the solar power device. A DC-to-AC converter converts the DC electrical power into AC electrical power. A controller enables the DC-to-AC converter to receive a portion of the DC current electrical power from the solar power device only if all of the DC current electrical power cannot be consumed by the DC load.

主权项

1. An electrical power supply arrangement comprising:
a solar power device configured to convert sunlight into DC electrical power; an adjustable DC load configured to run on the DC current electrical power; an electrical output sensing device configured to sense a level of electrical output of the solar power device; and a controller coupled to each of the adjustable DC load and the electrical output sensing device, the controller being configured to:
receive a signal from the electrical output sensing device;adjust the DC loads such that the DC loads consumes a maximum amount of the electrical output of the solar power device, the adjusting of the DC load being dependent upon the received signal; andif the DC load cannot consume all of the electrical output of the solar power device, then cause a remaining portion of the electrical output of the solar power device to be converted into AC electrical power.
