    Understanding Capacitor Polarity in DC Converter Circuits

    Jim thanks for your answer. This is exactly what i want to ask. Yeah your explanatoin is very clear. So it means the capacitor polarity will be positive on the right hand sided during unit step response (switch close) and the polarity will be reverse when switch open ( natural response). Is it...

    Shore power supply for the vessel

    Hi all, I am facing the problem with shore power supply for the vessel. At our ship yard, sometimes we need to arrange temporary electric supply for the vessel meanwhile their generators are overhauled. For 440 V 60 Hz i am using portable generator supply and for 415 V 50 Hz supply i am...

    Understanding Capacitor Polarity in DC Converter Circuits

    Hi all, Please see the attach file. It is positive output LUO converter. at t=0 and let us consider switch is open. At that time, diode will be reverse bias and the current will flow through at first loop only (flow through inducotr L1 only0. But that time the capacitor C will be charged. Is...

    Understanding Capacitor Polarity in DC Converter Circuits

    Thanks for your reply dim. So if the capacitor connected seires to resistor or other circuit then the current can't go througt them too. One more question, if the capacitor get the open circuit voltage, is there any chance for it to discharge later. How about the inductor?

    Understanding Capacitor Polarity in DC Converter Circuits

    Hi all. Good day to you all. i want to make one thing clear. In converter circuits, how to trace the polarity of capacitor circuit. Is it following the polarity of capacitor or follow the current flowing in it? I understand that the capacitor is open at dc. So it means it is like a brake part in...
