I need to simulate a power supply that has a slow, 1.5 second startup, thanks to a NTC thermistor in the power lead. It also needs to current-limit at 3 amps. I've tried various combinations of a 3-amp current source, a diode, and a sawtooth, but they stil leave a lot to be desired. Any ideas? |

A search of CL for: ramped might give you some ideas or: https://www.circuitlab.com/circuit/ch23n3/behavioural-thermistor-01/ https://www.circuitlab.com/forums/general-discussion/topic/6bf3m8vy/urgent/#comment_3581 And this will give you a current limited voltage follower ... https://www.circuitlab.com/circuit/ns9k5b/cunning-current-source-01/ :) |
