Power transfer by IPT questions

AI Thread Summary
The user is attempting to charge a AA battery using a circuit designed for inductive power transfer (IPT) but is not getting any output readings. They suspect an issue with their circuit design and are seeking help with modeling coupled inductors in PSpice for simulation purposes. A response suggests checking the Multisim simulation settings to ensure it recognizes the voltage induction in the secondary circuit. Additionally, it recommends using transformer models instead of inductors, adjusting for the correct turns ratio based on the chosen inductances. Proper modeling and simulation adjustments are crucial for achieving the desired charging results.

I am using this circuit below to charge a AA battery at the receiver's output. i think it should at least have some readings but i was wrong. there was no results at all. is there something wrong in my design. I've took the basic circuit only(hadnt add the control devices).
PS I am a noob at pspice, can any1 show me how to model the coupled inductors as IPT in the simulation?
Thanks!

At first glance, it appears your Multisim simulation doesn't know that you're trying to induce a voltage into the secondary circuit.
The first obvious place I would double check, is your Multisim program, to see if they have models for transformers, and replace your two inductors with it. Use a turns-ratio appropriate for the 2 inductances you've chosen.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
