The Importance Of Current Sense Resistor In Switch Mode Power Supply

The current sense resistor is normally found in the switch mode power supply section. If you fix electronic equipment especially the switch mode power materials, the current sensing resistor is linked to the source pin of power FET (field impact transistor) and the other end to HOT GROUND. The worth of the current sense resistor is in the variety of 0.1 ohms to about 1 ohm. In some cases where overload happen-the power section will blow and many of the time the elements altered are the fuse, power feed, PWM IC, Zenner diode and current sense resistor.
