   Field Programmable Gate Array Based Control of Dual Active Bridge DC/DC converter for the UNIFLEX-PM Project
By Alan WATSON, Patrick WHEELER, Jon CLARE [View]
[Download]

Abstract: This paper presents a Field Programmable Gate Array (FPGA) implemented control system for a DualActive Bridge (DAB) DC/DC Converter. This implementation was required during the UNIFLEX-PMproject to reduce the required computational burden on the Digital Signal Processor (DSP) used for thegrid power flow control algorithms. The presented design is verified using one of the 25kVA Dual ActiveBridge DC/DC Converters from the UNIFLEX-PM experimental prototype.

   High Performance Stationary Frame AC Current Regulation Incorporating Transport Delay Compensation
By Brendan MCGRATH, Stewart PARKER, Grahame HOLMES [View]
[Download]

Abstract: This paper presents an enhanced stationary frame PI current regulator that uses feedback of the controller/ modulator transport delay to significantly improve both the controller performance and its robustness to variations in load parameters. An improved anti-windup saturation strategy is then proposed to further enhance the system performance. Matching simulation and experimental results demonstrate the controller’s superior transient and tracking performance compared to a standard PI implementation.

   Triangular Carrier Self-Alignment Using Modular Approach for Interleaved Converter Control
By Marc COUSINEAU, Mathieu LE BOLLOCH, Nadia BOUHALLI, Emmanuel SARRAUTE, Thierry MEYNARD [View]
[Download]

Abstract: In this paper, a modular approach for carrier generation dedicated to interleaved converters is presented. These analog triangular carriers reach, in few hundreds of microseconds, a perfect shift in phase using an original self-alignment method. This property is obtained whatever the number of the converter carriers more than or equal to three. Main interest of this approach is to perform a masterless system which doesn’t use a central dedicated circuit. Because the modules are placed in a daisy-chain configuration, this method offers the ability to reconfigure very easily the number of carriers. An implementation of these carrier generators is made in a integrated circuit and demonstrates the validity of the proposed method.
