    Lead acid charging circuit for photovoltaic system

    Thank you, at this point I've been using LM350 to make a 7,4 V regulator for 6V VRLA battery. I use constant voltage charging method. But I don't how to limit the current while I also want to regulate the voltage at the same time. regards

    Lead acid charging circuit for photovoltaic system

    lead acid charger circuit I'm going to make a charger for lead acid with PV panel as supply. My panel is about 50 W, max 21 V and max 2.5 A. I need regulator or DC/DC converter. I think using adjustable regulator IC would be easier than using PWM buck converter IC. Is this true? If I use PWM...

    Why we avoid inductance for low frequency designing?

    Re: inductance in filter hmm that's explains again. the point is it's unpractical when it comes to physical circuit. thanks

    Why we avoid inductance for low frequency designing?

    inductance in filter So it's because we'll need high inductance for high resistances, in low frequency design. Thanks.

    Why we avoid inductance for low frequency designing?

    inductance in filter I'm studying amplifiers designing with op amp right now. when i saw filter circuits, there only capacitance were used. my lecturer said, it's because we avoid inductance for low frequency designing. he said some factor value will become great. but, i didn't understand. can...
