“…To protect each IGBT from overvoltage transients, an antiseries transient voltage suppressor (TVS) diode P6KE440CA is connected between the gate and collector of each IGBT 41 . The P6KE440CA TVS has a maximum reverse stand‐off voltage of 376 V and a maximum clamp voltage of 602 V, which is below the maximum collector‐emitter voltage of the IGBTs and body diodes.…”

The conventional topology of direct single‐to‐single‐phase matrix converter (SSMC) is widely adopted in industrial and power system‐related applications owing to its desired features. Current control methods in the literature either limit the voltage transfer ratio (VTR) or prohibit their utilization to drive inductive (RL) loads. In this study, we propose a novel control method that overcomes these limitations by enabling the SSMC to achieve relatively high VTRs while driving RL loads with negligible output voltage spikes and without current commutation problems. Further, the proposed control method improves the overall performance by reducing output voltage and source input current total harmonic distortion (THD) and offering soft‐switching at the commutation instances. The rigidity of the proposed control method over the counterpart methods in the literature is verified through simulation and experimental case studies over a wide range of synthesized output frequencies and modulation indexes. A 530‐W laboratory prototype is built for the experimental study. Results demonstrated the ability of the proposed method in enabling the SSMC to drive an RL load without current commutation issues and with mitigated output voltage spikes while achieving relatively high VTRs and suppressing the output voltage and source input current THD.

“…In addition to the clamp, many other overvoltage protection schemes have been studied. One proven scheme is the inclusion of varistors across the input and output lines of the matrix converter [5]. Another proven method is the addition of suppressor diode protection to each IGBT that is activated by voltages slightly lower than the switch voltage ratings [5].…”

An overview of the matrix converter and standard protection strategies is presented for an understanding of the matrix converter and its currently implemented protection strategies. New protection methods are then proposed for downstream faults to reduce their severity and to buy enough time to fully protect both the matrix converter and sensitive loads. The goal of implementing new output protection strategies is to be able to utilize the matrix converter in future distributed generation applications. The proposed methods are based on the addition of a standard protective relay and circuit breaker combination at the output of the matrix converter along with generator neutral grounding resistance and a zero voltage output command. Simulation and hardware testing results are then presented in order to verify that the new methods will protect the matrix converter and downstream loads while adding additional selectivity and diagnostic capabilities.

“…A diode-clamp protection circuit with a capacitor is often used [11] but this solution is expensive and bulky. Some solutions have been proposed to address this issue including varistors [12], active clamping [13] or shutdown commutation sequences [14]. Although it seems that none of these solution is widely used.…”

International audienceMany research efforts have been dedicated to matrix converters for several years. As major technological issues are now solved, this structure will widespread in industrial applications, in particular with AC motors. Current control is a key issue for AC motor drives, so many control schemes have been proposed. Some of them proposed at first for inverters, were applied to matrix converters. Among algorithms used with inverters, predictive control shows very good performances. In this paper a new control scheme is proposed for a matrix converter- fed permanent magnet synchronous machine. Literature about matrix converter technology and control and about predictive control for inverter-fed AC machines is reviewed. The proposed predictive control principle, the model of the whole machine - converter and the cost-function are detailed. The method offers a trade-off between the quality of motor currents and input power factor. Finally experimental results are reported. The feasibility and the effectiveness of the proposed method is assessed

Passive protection strategy for a drive system with a matrix converter and an induction machine

Abstract: In this paper, the design and testing of a new protection strategy for a matrix converter feeding an induction motor with a squirrel cage rotor is described. The new protection strategy with excellent overvoltage protection allows the removal of the large and expensive diode clamp.
