    9v - 200V flyback design guide

    9v to <200v converter Thanks, the output current should be 15mA to have an output power of 30 watt and the input power is 35 watt with efficiency of 85%. The input current is 4A. I need to measure the current in primary side. Also, I need to measure the capacitor output voltage but through an...

    Electrode high voltage protection

    I want to continuously measuring the ecg signal from a patient by connecting two electrodes to the chest. However, at the same time the patient is subject to receive a defibrillation shock of > 1000 volts. How to protect these electrodes against this high voltage shock, and thereby protect the...

    9v - 200V flyback design guide

    flyback and a 9v thanks for the advice, but i still do not know how to build the system, i mean how to build the converter using this IC. Also, if any one know how to simulatesuch kind of circuits in orcad since I found a already built converter but i could not simulate it in orcad. thanks
