The Importance Of Current Sense Resistor In Switch Mode Power Supply

The current sense resistance usually placed on how to modify food. The latest version tracking b + (speed) circuit also has this perception of the current opposition. If the repair of electronic equipment in particular how to switch power supplies, the resistance of the sensor is connected to the power pin fat (transistor field-effect) and the other in Tierra Caliente. Present value meaning of resistance is around 0.1 ohms at about 1 ohm. The values depend on the design of each source of energy. The screen where food pulse width modulation (PWM) IC UC3842. Pin 3 of this force is called I-ic current perception of what is meant by common sense and this PIN is connected to pin the source of power bold. The purpose of this course is the importance of circuit protection against overcurrent. This tour shows spenningsfall usually a strength of the series switching transistor bold. If the current rise abnormally because of some short-circuit in the secondary, as a diode short-circuited secondary or transistor output horizontal (HOT), the action exceed a benchmark and the pulse generator which is PWM IC. This circuit offers protection for components in case this happens. In some cases, overloading happens force the coup and most of the time they changed the ingredients are fuses, energy, fat, PWM IC, Zener and the current direction of resistance. Do you know that a small change in the current sense resistance value have a significant impact on production is secondary? A small change in the value of say 0.22 - 0.44 ohm ohms could cause production to spenningsfall the middle! I have seen a lot about workshop does not detect such problems (low voltage output) because they were using analog or digital meters that do not have low ohms. You can not separate the low-ohms of resistance has changed its normal value using meters. Personally, I use the Dick Smith Meter international search report which have the ability to see the value of resistance until 0.01 ohms! If you do not have meters that can not directly replace the current meaning of resistance to see if the result product back to its normal voltage. Another tip is that if the current sense resistance on the screen B + circuit has changed the value which caused the departure of progress in the circuit at a low level, you have a small screen width, and of course The tension is too low. Instead of 24kV is 15-18Kv. Jestine Yong is an electronics repair shop and a writer.
