    1VAC to 1VDC converter using OPAMP

    It should not vary. It is only 1V I need DC at the output. I will try to use another OPAmp. Thanks.

    1VAC to 1VDC converter using OPAMP

    Need help in making 1VAC to 1VDC converter. I tried to simulate on PROTEUS different OP-AMP circuits available on net. But not working. it always give high voltage(supply voltage) at output when input is given 1VAC. May pls. help.

    Voltage Drop Issue across Diode Bank.

    Hi, Thanks a lot for your valuable comments. So if i increase the Total voltage(at present 100VDC), Vf will increase (till i get Max Fwd voltage) across each diode so the Current according to vF vs If graph.

    Voltage Drop Issue across Diode Bank.

    Hi, I have Diode Bank of 100nos of Diode (SF4007) are are connected in series. My aim is to test this diode bank on full load. SF4007 has iMax =1A, Peak reverse voltage is 1000V. This Diode bank is connected to 30Ohm 300W resistance which is again in series. I am giving 100VDC to Anode of bank...

    UC3842 simulation problem in Proteus 8.0Version

    Dear experts, Please help me to findout simulation error. I am getting error msg as shown in attached pics. Circuit shown is to just check whether UC3842 is working in Proteus 8.0 version or not. Simulation does not stop but gives error. I doubt on Model UC3842 files (.MDF, .IDX, .LIB) which i...

    Looking for SG3524 or any similar PWM IC library for PROTEUS 7.8 ver.

    Looking for SG3524 or any similar PWM IC library for PROTEUS 7.8 ver. for SMPS simulation. It is not in Proteus 7.8 ver Library. I got .mdf/.Sec/.Dsn file for UC2524.But these file extension is not supported by Proteus7.8Ver. Can any one has PWM ICs library for Proteus 7.8 Ver 8-)
