PEBB Feedback Control Low Library. Volume 1: Three-Phase Inverter Control Algorithms

The Navy is actively engaged in developing Power Electronic Building Blocks (PEBBs) for its initiatives into DC Zonal Electric Distribution (DC ZEDS) . DC ZEDS is a key element of the Integrated Power System (IPS) effort which seeks to modify the current surface combatant so that both ship service and ship propulsion electrical loads are powered from a common set of prime movers. Presently, the current generation of PEBB-like devices include high-power, fast- switching, high-bandwidth dc-dc converters and dc-ac inverters. This report summarized the algorithms required to control a conventional three-phase inverter. First, implementation issues regarding the Sine-Triangle Pulse-Width- Modulation and Space-Vector Modulation are presented with an emphasis placed on digital realizations. Then, two current control schemes are documented via analysis, design example, and simulation. Next, a complex voltage-control scheme is documented, a design example proffered, and simulation studies conducted to illustrate dynamic response. The report concludes with detailed analyses, designs, and simulations of two three-phase induction machine startup and speed control algorithms.Naval Postgraduate School Monterey CA Dept of Electrical and Computer Engineering is the author of 'PEBB Feedback Control Low Library.
