Description	Pulse-width modulation (PWM) has been one of the most intensively studied areas of power electronics in the past three decades. The fast development of the switching capabilities of power semiconductor switches requires faster, more accurate and simpler modulation techniques. Although the digital implementation of a space-vector modulator is simple, the required computations for the pulse times and the corresponding execution times limit the minimum sampling time. The on-line implementation of the conventional space-vector modulator requires that at every sampling time the sector where the space-vector reference lie must be established, and pulse times must be evaluated too. It follows that the trigonometric function sin must also be computed on-line. In one possible form of the conventional implementation, the sine function is stored in a look-up table. However, this approach has well-known disadvantages. It is possible to use such technique, where the direct computation of trigonometric functions is Pulse-width modulation (PWM) has been one of the most intensively studied areas of power electronics in the past three decades.
