Re: Current Limiting Elements & MOV for SMPS
How to decide whether to go with NTC or Resistor (If SMPS is low wattage <20W)?
As NTC is more costly then Resistor.If Resistor to be selected what shall be the material?
Thanks,

Hi All,
Can any one share the design selection , calculation for current limiting element like Resistor or NTC & MOV required for SMPS?
Which current limiting element to be selected as SMPS input current is low approximately 200mA for 16W?
Thanks & Regards,

We are calculating the PV Power by measuring Voltage & Current then adjust Duty Cycle accordingly in Perturb & Observe method.But,the worry part is how to regulate the output Voltage of MPPT if we are going with Isolated Topology as the duty cycle depends on Input i.e PV Panel parameters...
Required external Pot to control Output Current & Voltage.
The rating required for Pot are as follows,
1)Maximum Voltage at output = 80Vdc Variable Rating required using Pot from (1V to 80V)
2)Maximum Current at Output = 2A Variable Rating required using Pot upto 2A
Which...
MPPT Parameters are as follows,
1)Power : 300Wp
2)Vin : 36Voc
3)Iin : 10A
Selected P&O Algorithm accordingly edited code.But,the question is how we can achieve Constant or Regulated Voltage at the Output side of MPPT?
Generally if we go with Flyback or Forward or with any other...

FvM,
So after calculating proper Bmax we can use ferrite core for 50Hz?
Can we use Bmax for 50Hz application 2000Tesla.
Thanks & waiting for knowledge enhancement,:thinker:
Dear All,
Why we cannot use Ferrite Material Core for 50Hz application instead of Laminated Cores?
IS it because of Viberating Sound or Magnetic Property?
Thanks & waiting for knowledge enhancement,:thinker:
Do we need to connect MOSFET driver IC with SG6858, as output source & sink current from SG6858 Flyback Control IC will be less?
But usually in SMPS why MOSFET Driver IC or external Totem pole circuit not required eventhough the SMPS control IC is not capable to drive MOSFET >100mA,because of...
Do we need to use Schottky diode at the output of flyback because of it small forward voltage drop & fast recovery time or normal diode can be used?
Voltage drop will matter but fast time matters in flyback?
Thanks & waiting for knowledge enhancement, :thinker:
