    Program explanation needed (decimal to binary conversion)

    Hi ,this is a part of decimal to binary conversion program and i can't understand the statement inside for loop some body explain me . for (c = 31; c >= 0; c--) { k = n >> c; if (k & 1) printf("1"); else printf("0"); } this is 32-bit binary output program . so c...

    PIC UART not working in proteus .

    hi i wrote program for pic uart in hitech-c and i am trying to simulate it in proteus and i need help .I used LCD to display data which i typed in virtual terminal is it works . what is virtual terminal in proteus . is it used to send and receive data from microcontroller . #include<htc.h>...

    relay selection help needed

    Thanks for quick reply . GU-SH-112D relay has 30V at 10 A in dc and 10A at 240V ac .is it max operating dc voltage is 30V ? or it fine to work more than 30V .I have to use it for 54V at 15A.

    relay selection help needed

    Help me to select a relay , i want to control it from pic microcontroller. So its coil voltage between (5 to 12V). It must handle 20A current at 55V DC on its contact.

    bootstrap circuit explanation

    How to select rating of the bootstrap capacitor . Is it 25V is enough or it should above drain voltage? and capacitance value?

    bootstrap circuit explanation

    somebody help me whether cap stores (gate+drain) voltage or it blocks source voltage(how) and only give gate voltage(ie turn on voltage +15 for n type power mosfet ). thanks

    bootstrap circuit explanation

    Hi i didn't understand how the flying supply (capacitor) gives higher voltage (i.e gate_voltage+drain_voltage) ..

    bootstrap circuit explanation

    Hi can any one explain me how bootstrap circuit works in high side mosfet triggering.I know for N-MOSFET gate source voltage should be 12V to be on. if it connected in high side how 12V is maintained across it because gate voltage should be higher than drain voltage. I have seen it with driver...

    buck boost converter hardware problem

    Hi,till now i encountered two problem in converter 1) my buck boost converter didn't boost voltage in hardware with increment of duty cycle . In output it shows only input voltage value what ever i gives. 2) I connected two 680uF capacitor in parallel to get 1.36mF . when i increase input...

    buck boost converter hardware problem

    yes sir, instead i connected 50 ohm , 10A rheostat across the capacitor . In hardware after i replacing diode input current reduced , before there was short circuit through inductor . I get 3A for 15V input . Is there any way to prevent overheating of capacitor?

    buck boost converter hardware problem

    Hi to recharge the battery can i connect directly across the capacitor or add any resistor in parallel with capacitor then i connect battery across it ?

    buck boost converter hardware problem

    Hi,my 330uF electrolytic capacitor oil leaks from its bottom and capacitor come out of its plastic sheet over it. while working with 14V input , 50% duty cycle and 2.7A input current . i connected capacitor in correct polarity. i don't why that happened .
