In this paper a novel algebraic real-time algorithm for implementation of sinusoidal pulse width modulation (SPWM) based on B-Spline carriers is introduced and discussed. B-Spline functions are used as carrier signals with the aim to to reduce harmonic content of the three phase inverter output voltage. This algorithm eliminates the problem of B-Spline recursive evaluation with convolution integrals or convolution sums in digital counterpart. The pulse pattern synthesis is made with the help pre-calculated duty cycle expressions. In this way the carrier signals have not to be really synthesized, hence the hardware and the whole inverter control system becomes cheaper, more reliable and affordable.The proposed control Algorithm effectiveness is finally verified by means of numerical simulations in different operating condition (e.g. for different values of the amplitude modulation index and for different values of the power factor) of a three phase inverter. Different values for voltage and current Total Harmonic Distortion (THD) are presented comparing the B-Spline SPWM control with the classical SPWM control with triangular carrier signal.

“…is a buck converter and can only produce a voltage that is lower than the dc bus voltage. Despite many different types of pulsewidth modulation methods [10]- [15], a three-phase VSI basically has six active states and two zero states. A zero state is produced when the upper three or lower three switches are turned on at the same time, shorting the output terminals.…”

The Z-source inverter, utilizing a unique LC network and previously forbidden shoot-through states, provides unique features, such as the ability to buck and boost voltage with a simple single-stage structure. The analysis and control methods provided in the literature are based on an assumption that the inductor current is relatively large, continuous, and has small ripple. This assumption becomes invalid when the load power factor is low or the inductance is small in order to minimize the inductor's size and weight for some applications where volume and weight are crucial. Under these conditions, the inductor current has high ripple or even becomes discontinuous. As a result, the Z-source inverter exhibits new operation modes that have not been discussed before. This paper analyzes these new operation modes and the associated circuit characteristics.Index Terms-DC-AC power conversion, inverters, power factor.
