“…The rectifier delivers eight states, consisting of two zero vectors and six active vectors. The complex diagram is split by the active vectors in six sectors with 60 degrees forming each hexagon, with voltage reference vector corresponding to a pair of two active adjacent vectors (T a , T b ) and a zero vector (T 0 ) of commutation time T s [17]. Commutation times are determined by the equations below:…”

This paper covers a new topology, a synchronous wind turbine generator, and a solar photovoltaic generator. The Permanent Magnet Synchronous Generator is linked to the grid by back-to-back voltage source converters (BtB VSC), consisting of a two-stage rectifier and a five-stage Neutral Point Clamped inverter, operated by the Space Vector Pulse Width Modulation technique. A solar photovoltaic system has a direct interface with the capacitor of the DC link of the BtB VSCs, with no additional DC/DC conversion stage, while the efficiency of the system is maximized. This work features a Perturb and Observe algorithm Maximum Power Point Tracking for to extract the optimum power from both wind turbine and solar PV generator. The application of Space Vector Pulse Width Modulation control scheme is used for harmonics compensation THD. A proportional integral regulator is used to regulate the DC link voltage. A prototype is tested under various conditions, wind velocity variations as well as under several photovoltaic solar isolations. The present work has been treated using Matlab/Simulink. Simulation results proved efficiency provided by this controlling approach: reduced distortion of harmonic and increased power factor.

“…Some of them address the modulation problem following a space-vector PWM (SVPWM) approach [26]- [30]. When the converter has more than three phases, the number of vectors increases exponentially, according to the rule l n (where l is the number of converter levels, and n is the number of phases).…”

“…In [28], a similar methodology is reported for a three-level seven-phase NPC converter. SVPWM formulation is also used in [29] and [30], where a methodology to solve the multiphase modulation problem is derived using a two-level approach. This approach uses a matrix formulation to calculate the duty cycles.…”

This paper presents a generalized PWM-based control algorithm for multiphase neutral-point-clamped (NPC) converters. The proposed algorithm provides a zero-sequence to be added to the reference voltages that contributes to improve the performance of the converter by: i) regulating the neutral-point (NP) current to eliminate/attenuate the low-frequency NP voltage ripples, ii) reducing the switching losses of the power semiconductors and iii) maximizing the range of modulation indices for linear operation mode. The control method is formulated following a carrier-based PWM approach. Hence, dealing with complex space-vector diagrams to solve the modulation problem for multiphase converters is avoided. The recursive approach means that it can be easily extended to n-phase converters without increasing the complexity and computational burden, making it especially attractive for digital implementation. The proposed method allows regulating the NP voltage without the need for external controllers; therefore, no parameter tuning is required. The algorithm has been tested in a four-leg NPC converter prototype performing as a three-and four-phase system and operating with balanced and unbalanced loads. Index TermsCarrier-based pulse-width modulation, multiphase multilevel converter, neutral-point-clamped converter, capacitor voltage balance.
