    I want to make a circuit that will control the charging of battery by using PWM. Can any one help me?

    Welcome to AAC.
    Is this a project?
    If so show us what you have done already.

    Why do you need to use pwm?

    PWM is only needed if you really require a higher charging efficiency than a linear regulator can provide.
    And you will need a feedback loop to control the current which is generally most easily done with an IC switching regulator chip.

    I heard a friend said that there is someone in Taiwan that he applied a patent about the charging method, it seems used 90% to do the charging work and used 10% to do the discharge work, he claimed that is the best way for the batteries.
