INTRODUCTION In recent years, the usage of power electronic converters has been increased due to more flexiblity and easy to controllable; also much suitable for various applications like industrial, medical, power system deregulation, electric energy transportation and railway application [1]−[8]. Generally for AC power conversion is divided into two stage process AC-DC-AC conversion with help of rectifier and voltage source inverter or multilevel inverter [9]−[14]. However, in recent days matrix converter becomes alternative for conventional AC to AC conversion system; it avoids extra converter in the system and minimize the harmonic during this conversion process. Matrix converter can convert variable voltage magnitude and variable frequency [15]−[19]. In the literature, different PWM implementations for matrix converters have been made; among these, space vector pulse width modulation (SVPWM) offers greater performance in comparison to other pulse width modulation (PWM) implementations [20], [21]. As a result, total harmonic distortion (THD) is reduced, applied input voltage is used more effectively, and other electromagnetic interference problems are also lessened [22]–[25]. In this paper, a novel SVPWM scheme for converting from three to five phases using a matrix converter is presented. The bidirectional switch used by the matrix converter decreases stress on the power
