    Schematics Variable current 12v 60A to 0A

    I am glad that you are recovering from the flu. I am going to read the article (your link) to get an opinion of the idea. About the residual voltage, it should be easy to have a shutdown of the pulses at the same time as the engine stops for any reason. This could be accomplished in many...

    I see, these where new to me. The once I have been in contact with where not SWITCHES they where used to measure current. When you said Hall effect IC I did not think switch. Sorry, my mistake! Well it looks simple enough to get them to work, I don

    The most common UPS:s where I work just have trickle charge at 27.6Volts and these batterys (Dual Panasonic 12V 14Ah) is changed every five years. When measuring voltage and voltage under load (40 A for 15s) on these recycles only 5 out of 50 show any signs of degradation. However there is a...

    sasi, Well the high point can be 13.75V without losing any water and the low point depends on how long you want your battery to live. Best tip here is the manufacturers recommendations for maximum discharge (minimum voltage). An alternative is to trickle at 13.75V and never shut it down completely.

    I did not analyse the complete circuit but if the battery is 12V then the LM7812 will not work here.

    Schematics Variable current 12v 60A to 0A

    Yes, I figured that was the case after I looked around in the Blanchard place. You just rest for a few days and it will pass. Pour some good stuff in your tea or coffee and you will feel much better shortly. It

    Schematics Variable current 12v 60A to 0A

    Is the residual voltage a problem; is the production of hydrogen greater than the idle consumption? So, the P-channel is hard to get at your location. The Blanchard site H-bridge has P-channel AND N-channel MOSFETs. I agree this gets a bit complicated compared to an ordinary bridge. Maybe...

    single phase controlled rectifier for DC motor

    Kevin, No not PWM, but phase control. If you have Power Point installed in your computer, here it is: http://www.eas.asu.edu/~karady/360_stuff/Lectures/360_Topic_7_Power_Electronics.ppt If not check the PDF, sorry that the pages are sideways. SCR_phase_cont..pdf

    Audioguru, Oh, I forgot to mention I have a ton of RFG50N05 so it would be nice if they were usable . Its not a must I can get some new if required.
