  • How To Determine Maximum Output Power of SMPS, How To Measure Output Current of SMPS. i explained in urdu hindi. when you want to know the maximum power handling capability of smps, we have to measure the output current and voltage. to measure current i connected 6.8 ohm 20 watt resistance and verified the voltage. i added one be one resistance of same value in parallel. when the output voltage started to drop and fluctuation, that is the maximum output current
    i connected 14 resistors of 6.8 ohm 20watt in parallel, so RT is 6.81/14= 0.485 ohm
    total voltage= 12 volt
    Total current= 12V/ 0.485 Ohm = 24.74 Amper
    Total Power output = VxI = 12*24.74 = 296.90 Watt
    or we can find current in other way
    Voltage = 12 volt
    current drawn by each resistance = 12/6.81 = 1.762 amper
    14 resistance in parallel =1.762 Amper x14= 24.7 Ampere
