   A Novel Engine Generator System with Active Filter and UPS Functions Using a Matrix Converter
By ITOH Junichi; TAMADA Syunsuke [View]
[Download]

Abstract: This paper proposes the application of a matrix converter to a PM generator for power quality compensation, such as reactive power compensation, harmonic current and power interruption. The novel point of this work is that the matrix converter provides reactive power with harmonic current. Simulated and experimental results confirm that the matrix converter can maintain high performance as same as a conventional active filter and an uninterruptible power supply (UPS).

   Hybrid Cycloconverters: An Exploration of Benefits
By XU Tianning; KLUMPNER Christian; CLARE Jon [View]
[Download]

Abstract: Nowadays, power electronic converters based exclusively on IGBTs deliver excellent load side performance up to megawatt powers in the low voltage range (200-690V) and are steadily gaining performance in the medium voltage range as well. However, the medium and high voltage/high power range remains dominated by converters using naturally commutated thyristors (i.e. cycloconverters, current source inverters), which offer poorer output side performance. A new hybrid arrangement was proposed, targeting at the medium and high-power AC/AC range, comprising of a naturally commutated cycloconverter connected to a PWM Voltage Source Inverter, which has improved output voltage quality and is also capable of accurate control of the circulating current. This paper reviews this concept and investigates all other possible hybrid arrangements in comparison with standard cyclcoconverters in aspects of converter performance, cost and complexity to explore the benefits of this new arrangement.

Abstract: This work proposes a new intelligent power module integrating the bidirectional switch function with fast switching times, optimized for matrix converter applications. It includes the power transistors gate drivers, galvanic isolation between control and power stages, over-voltage protection devices, floating voltage power supplies and a control circuitry providing smart switching sequences for the current commutation strategy. In addition, its modular design allows easy replacement of damaged BDSs in an entire matrix converter and makes the power and signals interconnections easier. The structure of the bidirectional switch consists of a power substrate containing the power circuit and components (diodes, IGBTs, etc.) and a PCB on top with the control circuits. From the user's point of view, the proposed module shows two power terminals (bidirectional switch function), two pins corresponding to the voltage power supply of the high-level control circuits, the bidirectional switch logic control signal pin (turn-on / turn-off) and other auxiliary control pins depending on the implemented commutation strategy (for example, the sign of the load current).

   Matrix converter with advanced control for contactless energy transmission
By MECKE Rudolf; KÃœRSCHNER Daniel [View]
[Download]

Abstract: The use of a matrix converter for contactless energy transmission in the power range of several kilowatts reduces the number of energy conversion steps, avoids electrolytic DC link capacitor on the primary side, reduces losses in power semiconductors and enables sinusoidal line currents and a four-quadrant operation. In his application as a feeding converter a high output frequency is required (greater than 100 kHz). The transferable electric power and the efficiency of contactless magnetic systems can considerably be improved. Because of the high output frequency, high-performance signal processing elements are needed. To get a constant d.c. output voltage the matrix converter offers new concepts for regulating variables. The paper describes special aspects of new control and regulating techniques of the three phase matrix converter in combination with contactless energy transmission.
