A Pulse width modulation (PWM) rectifier
consists of three switching legs and remains one of the popular Power Factor
Control rectifiers. This paper proposes a new circuit topology for a
unidirectional multilevel PWM rectifier for AC-DC conversion. A PWM rectifier
can reduce the harmonic current dramatically because, the grid current is able
to control. The proposed method forms a new circuit which is the combination a
diode clamp-type topology and a flying capacitor-type topology. In this
topology, the number of switches and clamping capacitor and diodes are reduced.
Further, the proposed scheme can obtain good performance, as same as a
conventional multilevel circuit. This paper describes about the features of the
proposed topology; the Space vector modulation control strategy. The proposed
converter achieved a total harmonic distortion of 9.6% for the input current
and efficiency of 84.4% are simulated with Mat lab / Simulink model.
