    The current sense signal is an essential part of a current-mode switch mode power supply design; it is used to regulate the output and also provides overcurrent protection. The current sensing circuit for UC3843 in current-mode control provides the protection at full load operation and ads the current limiting facility in the design. The sense resistor RS monitors the current. it is connected at source pin of the mosfet and ground line of the dc rail. the all current have to flow through this resistance and it is causes to drop voltage across this sense resistance. thus these dropped voltage are fed to isense pin of the UC3842, UC3843, UC3844, UC3845, as the current reaches are at its peak primary current value, it detects the peak voltage for the current sense comparator, which immediately terminates the drive pulse until the voltage across this sense resistance drop below 1 volt. The UC384x family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error ampinput, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem-pole output stage designed to source or sink high peak current.

    Multimeters have their own internal resistance as well. That’s why when measuring the current sense with regular meter it will not show correct value. You need an oscilloscope or a true peak to peak measuring device.this guy is a real good teacher. Ty for showing us how to prove it. Well done.

    • @HaseebElectronics
      @HaseebElectronics  2 ปีที่แล้ว +1

      yes dear your right
      multimeters have internal resistance but that is much high so these don't effect too much,
      biggest effect is that the multimeters use RMS or TRMS sampling method and their high frequency is not good specially higher frequencies and duty cycle based pulses.so that's why we need oscilloscope to measure peak voltage or we need four wire measuring technique to get true rms value then we can convert in peak value by multiplying with 1.414

    I would expect the inductor efficiency adjustment to be 1/efficiency, meaning a requirement to increase the size of the inductor with a 10% reduction in efficiency. So, 0.9 should be in the denominator?

    Sir, thank you for the amazing videos, I have gained so much knowledge from following your explanations.
    Could you please make a video with focus on possible short circuits in the output side of SMPS? I am trying to fix my laptop adapter but unable to locate shorted component. In off board testing, output terminals of the adapter are showing continuity. For reference, I am working on a 135W, 20V Lenovo adapter using DAP019E IC(input side) and DAS01B IC & DAS05 IC(output side). I have checked all capacitors, MOSFETs and optocoupler after removing them from the board but the short still remains. I'm extremely motivated to fix this adapter and learn more about SMPS in the process. Thank you again.

      auxiliary voltage are to be calculated by checking the

      after winding, finally it can be adjusted by adding a current limiting resistance at vcc pin to compensate the difference in calculation and practical winding turns

    Haseeb
    Where did you obtain the duty cycle value of 48%? Because looking at the datasheet, max duty cycle for UC3843 states 100%. Is this a design choice? What if you were using UC3844 or UC3845 where in the datasheet it states max duty cycle to be around 48%?
    Secondly, there's not really a need to go back and forth looking for inductance L of the primary coil and plugging things back and forth. The Ipeak can be calculated from the simplified expression below because a lot of the expressions cancels out.
    Duty_cycle = t_on/t
    Ipeak = 2.5/Transformer_efficiency/Duty_cycle*Pout/VinDC_min
    Ipeak = 2.5/0.9/0.48*72/141.4=2.946A
    When choosing Rsense value, are we choosing for a value where Ipeak is below the saturation current of the primary coil? Also we are simply choosing a value from worst case scenario. Whereas in normal operational mode, we do not really approach this region?
    Lastly, I have a question about the scenario where the input voltage is 230VAC, what happens then? How do I figure out what current is running through Rsense? Does the duty cycle now change because VinDC is much larger (and the duty cycle is changed from the feedback loop of the SMPS)?
    Thank you.

    • @HaseebElectronics
      @HaseebElectronics  2 ปีที่แล้ว

      best regards and special thanks
      1. the Dmax for 3842/43 is 96% for CCM operation. but when we discuss DCM operation, then its duty cycle is limited upto 48% maximum, above than this the core drives in saturation
      2. as any power supply is calculated and designed in worst case scenario, Low line voltage & peak output power, in this situation the SMPS controller must utilize its maximum duty cycle
      when the line voltage will increase, the SMPS controller will change its duty cycle to maintain regulation
      at that time the current in primary will not reach to peak, because in this situation the transformer works in linear region, because the magnetic fields is in building up stage

      @beny9564 2 ปีที่แล้ว

      @@HaseebElectronics OK thank you for the reply. Sorry, I'm not too familiar with the terms. . . DCM? CCM? Where do I see this in the datasheet?
      EDITED: Nevermind, I found in some other datasheet about Discontinuous Current Mode and Continuous Current Mode.
      As for #2, ok that makes sense. So in the design scenario, I have to make sure that my selected PWM chip will be able to output the duty cycle at the higher line voltage?
      I have an issue with a SMPS circuit and I can't seem to figure it out. It's a Ridgid charger that was designed to 110VAC with a PWM chip that carries the marking 6853M27 and JCS4N60FB MOSFET. I was trying to modify the charger so it would work up to 230VAC. It partially worked when I changed out the bulk capacitor and MOV at the high-side input to be suitable for 230VAC line voltage. The charging circuit was shutting off but there were no sparks or short circuits. Turns out later I found out that the auxiliary winding of the transformer that is providing Vdd to the PWM chip was too high of a voltage causing the PWM to go into OVP and shutting off.
      However, when I was probing, my probe accidentally slipped and short a leg of Rsense to GND of the PWM chip. This caused the MOSFET to short circuit failure between Drain and Source, I believe my Rsense resistor went into open circuit and a few rectifier diodes on the high side also went into open circuit. When I was trying to fix it, I I replaced components with what I believe are suitable substitutes but I can't seem to get the board to work again without something short-circuiting or blowing. I was wondering if you might be open to help with troubleshooting? I can provide more details and circuit diagrams/picture of the board etc. But if you're too busy, I also understand. Thank you!
