Copy of Three Phase Power System - on Thu, 10/31/2024 - 23:41 Designer251391 × Member for 1 year 4 months 2 designs 1 groups Welcome to the community!! https://explore.partquest.com/node/676627 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/676627"></iframe> Title Description <p>This example three-phase power distribution system uses a variety of load types to create realistic static and transient grid-loading conditions and system asymmetries. These include constant power and variable resistance loads, lamps and motors with complex start-up load current profiles, as well as imbalance in the generator, lines and transformers.</p> <p>The models provide not only the characteristic behavior of each component, but also internally track the power input, output and dissipation, per phase and in total, so that power flow can be easily monitored. This system can also be used to assess, for example, the potentially destabilizing effect of a constant power load. Its “negative resistance”, or inverse relationship between the input voltage and current, can be observed in the simulation results by zooming in on a few individual AC cycles.</p> About text formats Tags Three PhasePower Flow AnalysisDelta-Wye TransformerConstant Power LoadsMotor Start-upInduction Motorlamp in-rush currentMechatronics Select a tag from the list or create your own.Drag to re-order taxonomy terms.

Loudspeaker with Simple Amplifier Designer258679 × Member for 6 months 8 designs 2 groups Welcome to the community!! https://explore.partquest.com/node/675959 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/675959"></iframe> Title Description <p>This "Live" example design includes a simple analog electronic amplifier, intended only to demonstrates the importance of multi-discipline system modeling.</p> <p>A swept frequency response test, from 40 Hz to 1000 Hz, shows the effect of the complex amplifier loading by the voice-coil and speaker-cone dynamics*. The electro-mechanical resonances strongly affect the current that must be supplied, in order to maintain a flat (controlled) output voltage over the specified frequency range. For example, the current in the voice-coil reaches a null at time 0.1 seconds, which corresponds to the effective "spring-mass" resonance frequency (60 Hz). The loudspeaker reaches its minimum impedance around 600 Hz, or at 0.6 seconds where the peak load current is observed.</p> <p>The simulation results also show that the average power (q1/npn/pwr_avg) in the BDP947 BJT exceeds its 5 Watt rating across the entire range, but especially at lower frequencies. The red "hot part monitor", with the junction to ambient thermal resistance set to 10 C/Watt, as given in the datasheet, shows the part temperature rising to over 100 C. These diagnostic indicators make it obvious that we need a bigger transistor!</p> <p>All of the parameters in blue can be changed by the user and a new simulation run. The updated scope waveform results will show the effect of that change. You can change the electrical resistance and inductance of the voice-coil, as well as the speaker cone mass and linear spring rate that affect the resonance frequency.</p> <p>* Note: Please refer to this companion example, that shows the input impedance frequency response of the loudspeaker alone:</p> <p>https://www.systemvision.com/design/loudspeaker-only-frequency-response</p> About text formats Tags LoudspeakerAmplifierelectro-mechanical resonanceBDP947NCV20071 Op-AmpBDP947 NPN TransistorMechatronicsmagnetic actuator Select a tag from the list or create your own.Drag to re-order taxonomy terms.
