no.... i am not able to calculate the bobbin pins, core area,
i need to design the whole ferrite transformer....
current through input transformer is 1A...
i m attaching my circuit diagram...plz take a look at it
i m using buck converter.... where after switch (transistor) i m using transformer for isolation...it is not a exact forward converter....
my Vinmin=10V, Vinmax=40V, switching frequency=52Khz, Vout=5V, Iout=1A
I am using TL594 as a feedback pwm controller.... i am not able to decide bobbin...
HELLO,
My name is Yadnesh Samant. Currently i m making BE project on Isolated SMPS e.
I need a ferrite core transformer with following specifications:-
Shape=>E-I core (ferrite - core transformer)
Vin= 7.5 volts to 8 volts
Vout1= 7.5 volts
Vout2=5 volts
frequency=52Khz
Nprimary= 17 turns...
Hello sir,
My name is Yadnesh Samant. Currently i m making BE project on Isolated SMPS .
we need a FERRITE CORE TRANSFORMER with following specifications:-
Shape=>E-I core (ferrite - core transformer)
Vin= 7.5 volts to 8 volts
Vout1= 7.5 volts
Vout2=5 volts
frequency=52Khz
Nprimary= 17 turns...
i m trying to design a isolated buck converter that will give me 5v fixed output
Vin= 7v to 30V.
i want to desing a pwm whose output is connected to transformer.
PWM receives i/p from optocoupler which gets i/p from the output of buck converter.
It would be very nice of u if u help me in...
