6 FAQs about [Constant power mode for outdoor power supply]

What is constant power mode?

While operating in Constant Power mode, the voltage is controlled such that the output power remains constant. In Figure 7 we keep our original voltage set point of 48V, the current setpoint of 80A, but now program the power set point to 1 kW. For each load resistance shown, the product of the output voltage and current equate to 1kW.

What is constant voltage mode?

In Constant Voltage Mode, a power supply will output a set voltage across its entire load range. Figure 1 depicts a graph of Voltage vs. Load Resistance for a power supply programmed to 48V with a current limit of 80A. Note how the voltage remains constant from no load to full load.

What is constant current mode?

Constant current mode is essentially the opposite of constant voltage mode. In constant current mode, also known as current-controlled mode, the power supply behaves like a current source, holding the current flowing through the output terminals constant while the output voltage varies depending on load conditions.

Can a DC power supply switch between constant voltage and constant current?

This article primarily applies to DC power supplies that can switch between constant voltage (CV) and constant current (CC) mode automatically. Many of B&K Precision's DC power supplies are categorized as this type of power supply, and depending on the application it is important and useful to know how to switch between the two modes.

How does a constant power supply work?

Discharge time is Toff=L.Ipeak/ (VOUT-VIN), and energy delivered to output is Vout.Ipeak.Toff/2 A true "constant power" supply would output infinite current into a short, and produce infinite voltage across an open-circuit; in practice, any supply is going to have a limit to the voltage and current it will produce, regardless of output power.

Which power supply has a constant power mode?

There are commercially available power supplies that have a constant power mode. An example is the Sorensen SG Series. There is another way of producing an approximate constant power source, which is useful if your load changes with temperature. If you put a series resistor of the same value as the load then the power evens out.
