As a new kind of compact-sized, bi-directional power flow AC/AC converter, indirect matrix converter draws wide attention in the field of aircraft power system, distributed generation and other industry application. This paper applies indirect matrix converter to permanent magnet synchronous generator system. The generator is connected with voltage source converter, control strategy of d-q axis closed loop control of load voltage and generator current of boost generation is discussed. The feasibility of the control schemes is verified by simulation results.

“…However, bulky and limited-lifetime DC-link electrolytic capacitors are still often considered as the disadvantages of B2B converters. Hence, matrix converters (MCs) [4]- [17] are commonly investigated as a possible alternative for B2B converter since only a small or no dc-link capacitor is involved in the MCs topology. This is especially beneficial for applications where volume and weight restrictions are required.…”

“…Alternatively, references [17] and [18] proposed an implementation of a reverse power flow operation of IMCs to generate a voltage-boost property. This configuration is an attractive solution for DG applications as it achieves a voltage gain larger than 1.4 just by reversing the order of the IMC to have a current source converter at the grid side and a voltage source converter at the side of the power source.…”

Model Predictive Control for Indirect Boost Matrix Converter Based on Virtual Synchronous Generator

et al. 2020

Indirect boost matrix converter is potentially a great alternative to a back-to-back converter for permanent magnet synchronous generators based distributed generation since it can achieve a voltage-boost functionality without utilizing a bulky DC-link capacitor. Despite the success of the indirect boost matrix converter topology, there still exist some issues in the relevant control structure that must be resolved appropriately. First, the existing controls are grid-following controls, which is incapable of islanded operation. Secondly, the exiting controls generate a highly distorted current waveform, which needs to be suppressed by a passive damping resistor. Moreover, without an energy storage element, the distributed generations have no short-time power reserve unit for providing an inertial power to support the utility. In order to solve these issues, a novel approach based on a modified virtual synchronous control and a finite control set model predictive control scheme is proposed in this paper. The former is adopted to ensure proper operations in both grid-connected and islanded modes and to emulate the virtual inertial response by drawing inertial power from the input source. The latter utilizes multi-controls of real-time variables to avoid complicated coupling between the input side and the output side controls and to grant the indirect boost matrix converter with the capability of providing active filter resonance damping. Comparative studies between the proposed control and its existing counterpart are conducted with several simulations in PSCAD/EMTDC software to demonstrate the superior performances of the proposed strategy. Finally, the proposed control is verified in a scale-down experiment testbed.

“…However, these methods require complex power circuits with complex control strategies. To boost the voltage without adding additional components, the reverse matrix converter (RMC) was presented in [7] and [8]. In these studies, it was determined that MCs can reverse the direction of power flow.…”

Reverse matrix converters, which can step up voltages, are suitable for applications with source voltages that are lower than load voltages, such as generator systems. Reverse matrix converter topologies are advantageous because they do not require additional components to conventional matrix converters. In this paper, a detection method and a post-fault modulation strategy to operate a converter as close as possible to its desired normal operation under the open-switch fault condition in the rectifier stage are proposed. An open-switch fault in the rectifier stage of a reverse matrix converter causes current distortions and voltage ripples in the system. Therefore, fault-tolerant control for open-switch faults is required to improve the reliability of a system. The proposed strategy determines the appropriate switching stages from among the remaining healthy switches of the converter. This is done based on reference currents or voltages. The performance of the proposed strategy is experimentally verified.
