如何将恒定电压设置为恒定电流

嗨，没有办法将设备设置为在恒定电流模式下运行。
电源将采用CV或CC，具体取决于您正在测试的设置和设备。
您可以控制的设置是电压和电流限制。
欧姆定律指出V = R * I，这将决定电源的模式。电源将处于CV状态，直到欧姆定律规定的电流超过电流限值。
然后该单元将处于CC模式。
让我们看一些例子：示例1.电压设置= 5 V电流设置= 6A，1欧姆电阻器单元将处于5 A的CV（I = V / R）示例2.电压设置= 5 V电流设置= 6A
具有.5欧姆电阻的OCP按照欧姆定律，如果单位为CV，电流将为10 A，但我们的电流限制仅为6 A.在这种情况下，该单元将进入6 A的CC模式（和电压
将在3 V）。
如果这是有道理的，请告诉我。

  Hi,

There is no way to set the unit to operate in constant current mode.  The power supply will be in CV or CC depending on the settings and the device you are testing.  The settings that you have control over are the voltage and the current limit.  Ohm's law states that V= R * I and this is what will determine what mode the power supply is in.  The power supply will be in CV until the current dictated by Ohm's law exceeds the current limit.  Then the unit will be in CC mode.  Let's look at some examples:

Example 1.  Voltage setting = 5 V Current setting = 6A with a 1 Ohm resistor
The unit will be in CV at 5 A (I=V/R)

Example 2.  Voltage setting = 5 V Current setting = 6A OCP with a .5 Ohm resistor
By Ohm’s law, if the unit was in CV, the current would be0 10 A but our current limit is only 6 A.  In this case, the unit will go into CC mode at 6 A (and the voltage would be at 3 V). 

Let me know if this makes sense.

嗨MattC，谢谢你的回复。你的解释对我来说很有意义。

  Hi MattC,

Thanks for your reply.
Your explaination makes perfect sense to me.
