Hi everyone; I need to learn how drop-in type switched mode transformers are being soldered in wave soldering process. The specific application details are listed below: * The application is slim product of lcd tv. * Due to slim design, the power supply should also be slim !! * The maximum...

Hi everybody Is it possible to obtain sawtooth signal output from a single op-amp with DC input voltage? I know that it's possible with 2 op-amps but my aim is to use just one. Could you recommend any circuit schematic or website? Thanks a lot.

Could anyone send me a table or URL which includes current carrying capacities of copper conductors for low DC voltages. Specifically, i need a cable with 150V 1A carrying capacity. The cable should include multiple thin Cu conductors (1 mm thickness each)enclosed with pvc shield. For example...

Hi everyone; I want to keep the supply to an IC within 8-20 volts interval while the possible DC supply occurs within 10-30 volts from a battery. I used a 2.4 volts zener diode in series with the Vcc pin of IC to achieve the lower limit 8V theoretically but unable to limit the supply to IC to...

Is there a graph indicating temperature vs. efficiency for a 1500 kVA 31500/400 V transformer?

Hello everybody; We want to use 2 squirrel cage induction motors connected parallel for a water pumping station. At normal operation, only one motor will be running, and if necessary the second one can be started. The rating of each motor is 370 kVA, 3-phase 380 V with minimum 0.85 PF. My...

Is the efficiency of an induction motor the ratio Tout/Tin or Te/Tin or in other words; what is the difference between electromagnetic torque and output torque of an induction machine?

As known; rotational losses in an asynchronous machine includes; * Core Losses * Friction & Windage Losses * Stray Losses (Miscellaneous Loses) For an asynchronous MW size generator; are all the rotational losses constant for all operating conditions? In other words; can we say &quot...

Can anyone help me about how to calculate the moment of inertia of an object? In my case, I want to find the moment of inertia of a 1.4 MW wind turbine rotating parts (high & low sped shafts, gearbox, generator rotor). Thank you.

Can anyone give me some links to learn about flip-flops, their working principles. Thanks

Anyone can help me to have induction machine formulations? My aim is to design an induction machine using its formulas. Thank you.

I want to design an induction generator on MATLAB-Simulink for a wind power application. Can anyone tell a tutorial or a made simulation of induction generators? Their torque-speed response, design parameters etc. Thank You.

Hi I'm trying to export output values from Simulink to an m-file. But although it seems OK, I couldn't be able to get data from m-file? Please explain how to use it or send an example file which I can check.
