Copy of CAN Network Signaling - on Thu, 09/05/2024 - 22:42 Designer258249 × Member for 6 months 3 weeks 0 designs 1 groups Welcome to the community!! https://explore.partquest.com/node/669975 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/669975"></iframe> Title Description <p>This 4-node CAN network model is a "Live" design, meaning the user can change or "tune" various parameters shown in blue, and then run a new simulation to see the corresponding change in the signals received at each CAN node. These "tunable" parameters include the transmission line lengths, termination and choke parameter values, as well as select which of the CAN nodes is the transmitter.</p> <p>In the network configuration shown, the parasitic capacitance at Node 4 causes asymmetric transitions. This asymmetry would normally result in EMI-causing even-mode propagating currents on the transmission lines, but the choke greatly reduces this effect. One interesting change the user can make is to set the choke inductance values to 0.0, effectively removing the choke from the network, and note the increase in the even-mode voltage wave on the adjacent transmission line.</p> <p>The user can also save a copy of this design and enjoy full editing capability of the network configuration.</p> About text formats Tags CANSignal IntegrityEMITransceiverchoketransmission line Select a tag from the list or create your own.Drag to re-order taxonomy terms.

Copy of Transient Stability Testing of Transmission Line Fed LED Driver - on Tue, 07/30/2024 - 19:58 Designer257600 × Member for 8 months 1 designs 1 groups Welcome to the community!! https://explore.partquest.com/node/663043 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/663043"></iframe> Title Description <p>This is a companion example to the design: "TDFS Impedance Stability of Transmission Line Fed LED Driver - Switching". In this version, a switch is added to turn on two of the LEDs after 2 ms, to inject a load transient into the system. This transient will expose the severity of the damped ringing response at the converter input, or system instability if the source/load impedance ratio is inadequate.</p> <p>The initial configuration for this design uses a cable length of 400 meters with 8 AWG = 2.1 mOhm/meter conductors, and a converter input capacitor = 22uF. This is consistent with the companion design. You can try using an increased cable length (e.g. 800 meters, 5 AWG = 1 mOhm/meter) by making a copy of this design and re-running the simulation. You will see that the circuit becomes unstable at that longer length. You can also try larger values of input capacitance, to mitigate the instability problem.</p> About text formats Tags Buck ConverterConstant Power LoadsSwitching ConverterLEDtransmission lineStep-DownTDFS Impedance Stability Select a tag from the list or create your own.Drag to re-order taxonomy terms.
