   A 20 KW MATRIX CONVERTER DRIVE SYSTEM FOR AN ELECTRO-MECHANICAL AIRCRAFT (EMA) ACTUATOR
By WHEELER Patrick; EMPRINGHAM Lee; KEARNS Paul; WHITLEY Chris; DE LILLO Lilliana; CLARE Jon; BRADLEY Keith [View]

Abstract: This paper describes the design, construction and testing of a 20 KW Matrix Converter driven electro-mechanical actuator for an aircraft rudder demonstrator. The converter has been built using three custom designed modules each one containing a number of 600 V, 300A IGBT’s and diodes sufficient to form a single output phase together with back to back diodes to detect the output current direction used in the commutation strategy. Practical results are shown. Description of the control structure, power circuit design, over voltage clamp circuit and practical results of the converter operating as an actuator position controller are presented.

   Active Three-Phase Rectifier for Aircraft Equipment
By GATHMANN Thomas; WOLF Henrik [View]
[Download]

Abstract: With the introduction of the variable frequency (VF) supply system in today’s aircraft like the Airbus A380, the restrictions on the distortions produced by electric equipment have been intensified. To meet these requirements, the conventional six-pulse diode bridges for three-phase loads have to be replaced by suitable concepts which lead to a near resistive input behaviour of the power electronic stages. This paper proposes a 2kW active three-phase rectifier for an electric drive integrated into the Trolley Lift Conveyance System of the new Airbus A380.

   High Frequency Power Converter for PEFC Generator Architecture based on a Multi Stacks Association for Transportation Applications
By PERA Mari; KAUFFMANN Jea; COQUERY Gerard; LALLEMAND Richard; GARNIER James; DE BERNARDINIS Alexandre [View]

Abstract: This paper presents the study and experimental validation of a high frequency (HF) power converter used in a powertrain composed of a Polymer Electrolyte Fuel Cell (PEFC) generator based on a multistack association and dedicated to transportation applications. As a first approach, the architecture of the system presented in this paper has been limited to two fuel cell stacks. An original power converter structure using a HF transformer (HFT) has been chosen. This structure has the main advantage of compactness and is well adapted to the testing of fuel cell generators either in normal or degraded mode (partial failure of one stack); which correspond to real transport operating conditions. Simulation results of the power system are presented and discussed. First experimental results for a normal PEFC working mode are presented and analyzed in this paper including the experimental determination of the power converter efficiency.

   Sensorless Permanent Magnet AC Motor Drive with Near Zero-Speed Operation for Electric-Assisted Bicycle
By RAUTE Reiko; ERTUGRUL Nesimi [View]
[Download]

Abstract: This paper presents a high performance electric-assisted bicycle system, where the rotor position is obtained by a position estimation technique using terminal quantities of the motor, which has a capability of starting from standstill. The components of the drive system include a wireless torque feedback, an application specific reference torque generation and torque control. The paper explains the implementation details of the position estimation technique that utilize a motor control DSP and provides real time test results to demonstrate its capabilities under real riding conditions including regenerative braking.
