It presents then how to use space vectors to synthesize any output voltage with two or three-level inverters. A demonstration code example is provided and freely available.
The technique of controlling the power switches in the inverter is used by many different methods such as Hysteresis Current Controller; Sinusoidal Pulse Width Modulation; Discontinuous Pulse Width Modulation and Space Vector Pulse Width Modulation . Space vector modulation (SVPWM) is very different from other PWM techniques.
Space Vector Pulse Width Modulation (SV-PWM) is a modulation scheme used to apply a given voltage vector to a three-phased electric motor (permanent magnet or induction machine).
Space vector modulated voltage signals generated by SVM algorithm. The nature of the generated modulation wave with a double hump maximizes the utilization of the available DC bus voltage. This provides a better rated voltage output when compared with Sinusoidal Pulse Width Modulation (SPWM) technique.
Abstract: A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter.
It can be tested in simulation using imperix ACG SDK and validated in the laboratory with a B-Box RCP programmable controller and PEB half-bridge power modules. Space vector modulation is an alternative to the Carrier-Based modulation technique that is used in the Three-phase Voltage Source Inverter (VSI) application note.
On the basis of the general decoupling transformation matrix for an n-phase system, inverter voltage space vectors in the second two-dimensional subspace (x - y) are determined with Eq. (14.92): Thus, 32 space vectors of phase-to-neutral voltage in the x - y plane are obtained using Eq. (14.92) and are demonstrated in Fig. 14.33.
