“…The topology consists of a three-to-two input MC and a standard voltage source converter (VSC) at the converter output. The existence of a "virtual dc link" between the two stages offers possibilities, such as multidrive operation as well as the use of different pulsewidth-modulation patterns for the input and output converters [2], [3], to reduce losses and/or input current ripple. Moreover, changing the modulation strategy of the input converter can lead to a reduced "virtual dc link" voltage as reported in [10], where the simulation results shown illustrated that the scheme could lead to a decrease in the commutation losses of the output converter.…”

This paper presents a control strategy for a doubly fed induction generator (DFIG) using an indirect matrix converter, which consists of an input side matrix converter and an output side voltage source converter (VSC). The capability of the input converter to generate different "virtual dc link" voltage levels is exploited. The commutation of the VSI with reduced voltage is illustrated for operating points where the output voltage demand is low without any deterioration of the current control performance. The proposed method leads to a reduction in the commutation losses in the output converter and reduced commonmode voltage. For the input converter, soft switching commutation is obtained by synchronizing the input and output converter pulsewidth-modulation patterns. This modulation strategy is particularly applicable in DFIG applications because the required rotor voltage decreases when the DFIG speed is close to the synchronous speed. The complete control strategy is experimentally validated using a 2-kW rig.Index Terms-AC machines, machine vector control and space vector pulsewidth modulation (PWM), matrix converter (MC).

“…However, in some applications, the 2MC may be preferred to the direct matrix converter due to simpler and safer commutation of switches [6], the possibility of further reducing the required number of the power semiconductor switches [7], and the possibility of constructing a direct converter topology with multiple input and output ports [8].…”

A matrix converter is an ac-ac power converter topology that has received extensive research attention as an alternative to traditional ac-dc-ac converter. A matrix converter is able to convert energy from an ac source to an ac load without the need of a bulky and limited-lifetime energy-storage elements. The indirect three-level sparse matrix converter (I3SMC) is a new topology from this family that can synthesize three-level voltage in order to improve the output performance in terms of reduced harmonic content. This paper discusses the operating principles and a space-vector-modulation scheme for this topology. Simulation and experimental results are shown to prove the ability of this topology to generate multilevel output voltages as well as to maintain a set of sinusoidal balanced input currents. The performance of the converter is compared with the conventional matrix converter and an alternative multilevel matrix-converter topology in order to demonstrate the advantages and disadvantages of the I3SMC.Index Terms-Matrix converter, multilevel converter, neutralpoint-clamped and three-level converter.

Multi-drive systems can be used in situations where several motors are mechanically connected. Such systems have applications in both industrial and aerospace applications, where they can be used to provide system redundancy. In conventional systems the power converter for the motor drive is based on a rectifier and inverter, leading to the requirement for large passive components such as DC-link capacitors. This paper proposes a multidrive system based on a two-stage direct power converter. In this topology a direct converter uses two output stages with a single input bridge, eliminating the need for large passive components. Simulation results are included to demonstrate the feasibility of the proposed topology.
