modelDCPowerSupply
Simple model of a DC power supply cv - cp - cc
Information
This is a simple model of a DC power supply, as used in laboratories. It can only work in one quadrant, i.e., positive voltage, delivering current. It has three limitations:
- ConstantVoltage:
v = V0 - Rcv*(-i); - Constant Power:
P0 = v*(-i); - ConstantCurrent:
-i = I0 - Gcc*v;
Remember that current delivered by the power supply is negative.
