To improve the electromagnetic interference (EMI) performance of PWM controlled switching dc-dc converters, bi-frequency pulse width modulation (BF-PWM) technique is presented in this paper. The principle of BF-PWM modulation is illustrated and the characteristics of BF-PWM controlled buck converter operating in discontinuous conduction mode (DCM) are… CONTINUE READING
