To limit inrush current, an NTC thermistor is placed between the power supply and system (see Figure 1). Upon power on, the NTC thermistor provides high resistance to limit inrush current. As the inrush current drops, the NTC thermistor self-heats and its resistance drops to a low enough value to pass current through.
Figure 3: Fuse in output of power supply Constant Current Limiting. A common method that has been implemented to limit the output current from power supplies is to monitor the output current and reduce the output voltage when the current limit is reached while maintaining the maximum output current (Figure 4).
Pasqo. 2. 6. The trick is very simple and effective, adding an ideal diode to any voltage source with the Ilimit parameter set (along with Ron=0 for perfect ideal behavior) will limit the current sourced to the specified value. To also limit the current sink add another diode in parallel but reversed.
The real correct answer is, you probably got the wrong supply to begin with. There might be a cheaper option - basically, set up a power mosfet switch with a clock and pwm the connection to the load. You could do this at a fixed 50% duty cycle which would give you an average current of <20A.
In a constant current LED driver, the voltage of the power supply is varied within a range to limit the current drawn to a specified value. Current limiting resistors Current limiting resistors are connected in series with the LED. The current limiting resistors can be inserted in both series and parallel LED circuits.
General Description. This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30VDC. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 mA) to the maximum output of three amperes that the
2. LM317 is a bad choice. 18VAC in the secondary is ~25.4V RMS, if you regulate down to 1V at 1.5A that's 36.7W of dissipation which the device won't be able to handle without a few cubic meters (ish) of heatsink. - Adam Lawrence. Feb 23, 2014 at 1:06.
With the CC option off, the power supply outputs a constant voltage until it reaches the maximum current it can supply, just over 5 A. With the CC option on, the supply works as a typical CC/CV supply, but the buttons are used to set the current limit in steps of about 40 mA per press of the button.
