For heavy industrial drive applications, the direct matrix converter (DMC) solves the problems caused by the two-stage power conversion mechanism. Due to a lack of technological advancement, the control of multiphase drives operated by DMC is a significant cause of concern. This article thus presents a direct torque control (DTC) scheme based on space vector pulsewidth modulation (SVPWM) for a five-phase induction motor (FPIM) driven by a three-to-five ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$3\times 5$</tex-math></inline-formula> ) phase DMC. This proposed SVPWM-DTC employs the virtual vector (VV) concept to eliminate the effect of the <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$xy$</tex-math></inline-formula> component on <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$3\times 5$</tex-math></inline-formula> DMC output voltage space vectors. A novel approach is applied to analyze the effect of SVPWM-VV on the stator flux, torque, and speed of FPIM drive. Additionally, this SVPWM-VV regulates the input power factor of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$3\times 5$</tex-math></inline-formula> DMC.
