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.
Battery Charging: Supplying a fixed voltage to batteries, thereby ensuring efficient and safe charging cycles. Overall, constant voltage mode remains the standard for most applications where the voltage level must remain unaltered, reinforcing its status as a critical function in DC power supply design.
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.
Modern DC power supplies are designed to operate in multiple modes—namely, constant voltage (CV), constant current (CC), and, in some specialized applications, constant power (CP). These operating modes are not just technical specifications; they are fundamental features that ensure devices function reliably and safely under varying conditions.
The user of a benchtop DC power supply normally starts by configuring the output voltage, and in most cases the supply operates in so-called constant voltage mode because the supply delivers the same,
DC power supplies are indispensable in modern electronics, offering stable direct current to devices that require precision and safety. The ability to operate in multiple modes—constant voltage (CV),
Switch Mode Power Supplies (SMPS) are equipped with the ability to control their output characteristics based on either voltage, current, or power. Learn more.

In order to limit the output power, and therefore input power, a third operating mode is introduced: Constant Power (CP). While operating in Constant Power mode, the voltage is controlled such that the output power remains constant. In Figure 7 we keep ourSee more on astrodynetdi adaptivepower [PDF]
