Sparse matrix converter: Modeling and PWM control

Abstract

The matrix converter (MC) is an alternative ac-ac power converter by connecting directly input to output phases through bidirectional switches and without using any dc-link or energy storing element, therefore is called an all-silicon converter. Two topologies of matrix converter are established such as direct topology and the indirect topology. This paper is devoting to presents the topology of the indirect sparse matrix converter (ISMC). So, the three phases to three phase sparse matrix converter (SMC) topology fed an RL load is modulated using the Pulse Width Modulation technique (PWM). Simulation results are shown to prove the usefulness of the control scheme.
