Efficient operation is a recommended factor in most of industrial applications. In this paper, an indirect matrix converter (IMC) topology is developed and proposed to substitute the classical (AC/DC/AC) three phase converter topologies; where the control strategy is frequently performed with a voltage source inverter (VSI). Large electrolytic capacitors are viewed as hazardous due to their short lifetime compared to ordinary capacitors and power switches, as well as their contribution to the total bulk and weight of the converter. Matrix converters may be the answer to getting rid of the capacitor, shrinking the converter, and improving its efficiency (MC). These advantages are offset by the fact that the (MC) calls for a tricky switching technique based on pulse width modulation, which is prone to commutation failure. The direct frequency conversion using the indirect matrix converter (IMC) with many advantages has appeared as an alternative to these conventional voltage inverters. This study investigates a field-oriented control (FOC) scheme for indirect matrix converter fed triple star induction motor (TSIM). After building the proposed IMC converter topology, an adequate field-oriented control strategy-based space vector modulation (SVM) is proposed and adapted for the control of the triple star induction motor. The FOC technique guarantees flux and torque decoupling while ensuring good operation performance as required in many industrial applications. The obtained numerical simulation results show and confirm the effectiveness of this control scheme.

“…However, the primary use of IMC over a traditional matrix converter is the simplified commutation process. All load side switches commutate like a standard DC/AC converter [14][15][16][17][18], but all line side switches operate at zero current.…”

“…Since the rectifier stage voltage vector v r and the inverter stage current vector i i are linearly dependent, two new switching matrices can be defined according to equation (12), resulting in (13). Rectifier voltage v C and inverter current i c can be expressed as a linear combination of the expressed vectors, hence the suppression in the new set of equations.…”

The insertion of powers sources onto the grid require an energy processing stage between generator and electrical grid, which adapts amplitude and frequency levels for alternating current (AC) quantities. The Indirect Matrix Converter is a candidate for such operation, although one of the greatest challenges of the topology lies in a way to command the switches while controlling the structure power-flow, as well as the synchronism between source-converter and converter-grid. Hence this paper presents a different view on the converter modelling and proposes a FPGA-based method to perform the Space Vector Modulation (SVM) and synchronism algorithms minimizing the resource consumption, focusing on digital processing algorithms and resource sharing to reduce resource consumption and the number of multipliers employed, ideal for implementation in low-cost FPGAs. Experimental results are shown using a prototype, demonstrating the efficacy of the implementation and verifying the converter behaviour.

“…Carrier-based (CB-PWM) and space vector modulation (SVM) are the two main types of pulse width modulation (PWM). 22 Although Wang 23 initially proposed carrier-based PWM, more study on the topic was conducted. 24,25 The first method for generating switching pulses involves comparing a high-frequency carrier signal (triangular) to a low-computing-effort reference signal (sinusoidal).…”

This study describes an indirect matrix converter (IMC) that uses symmetrical space vector pulse width modulation (SSVPWM) to feed two loads from a single DC link at a variable frequency. Output stage‐I is connected to the static load, while output stage‐II is connected to the PMSM for speed control. It is appropriate for drive systems with variable frequency, such as those seen in wind power generation and aviation. In recent years, significant studies on AC‐AC converters have been conducted due to the rising interest in electric cars and renewable energy. The performance of permanent magnet motors is better than that of other types of AC motors due to their superior performance and residual flux permanent magnets. Contrary to normal back‐to‐back power conversion systems, IMC does not necessitate the use of capacitors in the DC‐link, decoupled control between the two‐stages, a simple clamping circuit or zero current switching in the rectifier stage, allowing the system's volume to be reduced. It is investigated how well the two output stages of the proposed IMC perform. To illustrate the benefits of the suggested IMC design, an improved SSVPWM is employed, and MATLAB/SIMULINK‐based simulations were performed to validate the efficacy of the modulation mechanism. In addition, the real‐time implementation of the work was validated using a real‐time simulator, OPAL‐RT (OP4510).
