AC Induction Motor Control Using the Constant V/f Principle and a Space-vector PWM Algorithm

In a previous application note [AVR494], the implementation on an AT90PWM3 of an
induction motor speed control loop using the constant Volts per Hertz principle and a
natural pulse-width modulation (PWM) technique was described. A more sophisticated
approach using a space vector PWM instead of the natural PWM technique is
known to provide lower energy consumption and improved transient responses. The
aim of this application note is to show that this approach, though more computationally
intensive, can also be implemented on an AT90PWM3.
