hi,
i want to make a buck converter whose input voltage is 220v dc and i require 180 v dc almost 82% duty cycle.
help me out with different topologies which r suitable to use
i want to use adc of atmega32 and the perform some arithmetic and then emit a required pwm signal . i want to do all these works in a stipulated time so that i can update continuously. can anybody give links or throw some light regarding the topic
hey,
i am using a v-f converter to measure votage and i want to use atmega32 to measure the frequency so that i can get the voltage value from the frequency using simple arithmetic
problem is i dont know how to measure frequency continuously.
i have to update my value as my voltage change.
my...
hey,
i am using two adc channels . the problem is i have to update 1 channel continuously and for the other,one time conversion is enough.
i have to store the results of two channels seperately and compare them.
can anyone help me with code.
please,looking forward for help
can u post that inductor formula again (i.e how to calculate it)
by the way i am using irf 740,schottky diode
and i used this calculator but the values i got from ur formulas and this buck converter calculator r different

hello,
i want dc variational voltage from 100v to 180v from a 220 v input.
i am using a driver connected to mosfet and input of driver is connected to microcontroller which is generating pwm .i dont know which values of inductor capacitor to design it .
and comment whether my idea is feasible...
hi,
i want to know how to program for atmega 32 in avr srudio to generate a specific pwm and to vary its duty ratio automatically in steps until my error comparing a measured value wit reference value is zero please help me out

hey someone help me out .
i want required dc voltage from a 220v dc source using buck converter
i want to give a pwm signal to the mosfet gate through a driver from a micro controller
give links or explanations as i didnt get a clear cut picture
