Transformers and Electric power Ltspice

AI Thread Summary
The discussion focuses on troubleshooting energy conversion efficiency issues in an LTspice circuit involving transformers. The user reports that the output power (P2) is significantly lower than expected, achieving only 90% efficiency when the flyback diode is removed. Participants suggest checking the file format, advising to delete the ".dox" extension for proper viewing of the LTspice file. There is a request for a PDF screenshot of the circuit and analysis to better understand the problem. The conversation emphasizes the importance of file management and circuit analysis in resolving simulation discrepancies.

Hi, i was looking for the Energy conversion efficiency of my circuit in Ltspice, but i find out that my Transformers is giving me strange power values i mean with K = 1 the P1 should be equel to P2 but in my case P2 is is way too small , i get equality 90% only if get rid of the Flyback diode, can you please help me understand the reason behind this

why is your file saved as a .asc.dox ?

how should i save it? it is a an asc ltspice file delete the the .dox and you should be able to see it

Can you post a PDF of a screenshot of the circuit and of your analysis?

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
