Abstract
A control system, method, and device for managing variable power sources in DC power systems, such as photovoltaic (PV) systems. An electrical component can be configured to condition power from a photovoltaic (PV) panel such that current is drawn from the PV panel at a peak power continuously, at all times, or irrespective of current flux.
Claims19
A photovoltaic (PV) panel power conditioner, comprising:
- a circuit configured to increase a voltage of the PV panel to an output voltage;
- the electronic power conditioner being integrated into the PV panel and including a temperature sensor;
- the circuit being further configured to regulate the output voltage responsively to the temperature sensor such that current is drawn from the PV panel at a peak power irrespective of a current insulation flux.
An electrical component configured to condition power from a photovoltaic (PV) panel such that current is drawn from the PV panel at a peak power substantially at all times during operation, the component comprising:
- circuitry to increase an unregulated DC voltage from the photovoltaic (PV) panel;
- circuitry to regulate the increased DC voltage for output;
- and
- circuitry to modify the regulated and increased DC voltage for output, the circuitry to modify including a comparator that receives a first voltage signal from a temperature sensor representative of a temperature of the PV panel and a second voltage signal associated with the unregulated DC voltage, the circuitry to modify superimposing on the regulated and increased DC voltage a secondary voltage that causes the regulated and increased DC voltage to one of rise or fall, the rising or falling of the regulated and increased DC voltage causing current extracted from the PV panel to be altered.
