Application note

Space vector modulation using 8-bit ST7MC

microcontroller and ST7MC-KIT/BLDC starter kit

Introduction

Due to its compatibility for use in vector control (field orientation) of AC motors, Space

Vector Modulation (SVPWM) is one of the most widely utilized techniques to generate

sinusoidal line-to-line voltages and currents with a three-phase inverter.

This application note first illustrates the theory of Space Vector Modulation and then

describes an algorithm which can be utilized to implement SVPWM using the 8-bit

microcontroller ST7MC.
