In this case a 3A step current command is given to the ideal driver at the beginning of the simulation. The applied voltage is limited to the specified battery voltage, which is being swept from 12V to 48V in steps of 4V for this test. The blue waveforms show the solenoid current initial ramp up, caused by the inductance-limited di/dt at each applied voltage level. The orange waveforms show the corresponding solenoid (armature) position, or "pull-in" response, for those voltage levels, including the "bounce" as it impacts the hard-stop at the end of its stroke.</p> <p>If you plot those solenoid current waveforms in the main viewer and use the "LevelCross" (= 2.95) measurement option in the waveform analyzer tool, you'll see that most of the current rise-time improvement comes by raising the voltage to 24V. Above that voltage level we see diminishing returns in the time to reach the 3A target current level. This implies that a simple voltage doubler circuit may significantly improve injector turn-on responsiveness.</p> About text formats Tags Select a tag from the list or create your own.Drag to re-order taxonomy terms.
