LTspice simulation can be used to create a similar injection and measurement in the control loop for an LED. Figure 2 shows an LED driver (LT3950) with an ideal sine wave of given frequency (f) injected directly into the feedback path on the negative sense line (ISN). Measurement...
In LTspice, I-V data can be measured using the.DCSPICE command/directive. The ground clamp of DOUT1 is measured using the setup in Figure 4. In the setup, appropriate supply voltages were applied to configure the device in a high impedance state (please refer to ...
Triple click on the SpiceModel value which is “Coilcraft_Inductor” by default to get the dropdown menu of available values Once the value is selected and the inductor is placed in your circuit the simulation is ready to go Plotting Waveforms To plot Inductance vs frequency (best viewed in...
There are plenty of SPI ADCs that are easy to interface to FPGAs. My recommendation would be to first get your IGBT circuit designed in a simulation program like LTspice, using ideal voltage sources (configured for PWM generation if necessary), and voltage/current sense p...
TheLTspiceschematic shown above allows us to investigate the transient and steady-state behavior of the diode-based protection circuit. The power-supply voltage is initially at 0 V, then it abruptly changes to –3 V. My idea here is to simulate the effect of incorrectly inserting two 1.5 V...
The command line in LTspice is then set to be .noise V(VOUT) V1 dec 100 20 220. Then hold the control key and left click on the waveform name (V(ONOISE)/101). The rms noise can easily be converted to peak-to-peak noise using the equation: ...
