What is source sink concept?

What is source sink concept?

In crop plants, the physiological basis of dry matter production is dependent on the source-sink concept, where the source is the potential capacity for photosynthesis and the sink is the potential capacity to utilize the photosynthetic products. Sink size is the potential capacity for maximum production of crop.

What is the relationship between sources and sinks?

Plant organs responsible for taking up a particular resource from the environment are known as the ‘source’ for that resource, whilst organs utilising the resource for growth, metabolism or storage are the ‘sink’ for that resource.

What is the input power of a servo drive?

In a DC servo-driven motor, the input power is the electrical power provided by the power supplies or battery systems. When a single supply is used, P in can be calculated as: Where V bus is the power supply DC voltage (between POW_SUP and GND_P terminals) and I bus is the current provided by this power supply.

What is the difference between sink and source logic?

A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load. Logic is defined by the type of components in the circuit.

What causes power loss in a servo drive?

Power losses in servo drives are mainly caused by the power stage, which converts from a DC input supply to an AC output voltage. However, other blocks in the servo drive contribute to the power losses. Figure 3 shows a block diagram of the main power losses sources in a servo drive.

How are sink and source used in a circuit?

Sink and Source are terms used to define the flow of direct current in an electric circuit. A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load.
