The paper proposes a new control scheme for an ac-dc converter that will reduce the total harmonic distortion in the input current while operating at an improved power factor. The circuit uses a diode rectifier whose output is varied by a boost regulator with a second-harmonic injected PWM. An approximate analysis shows that the addition of a second harmonic component in the PWM helps to reduce the third harmonic in the input current. The design parameters are obtained using digital simulation. The results obtained on an experimental converter are compared with the ones obtained from a conventional scheme.
