In this paper, a method for removing the risk associated with the testing and development of novel drive system topologies, prototype electric machines, advanced control system strategies, or a combination of the aforementioned without using any real motors/generators is presented. For low power machines, the test platforms are relatively inexpensive and accessible, however, as power levels increase...
Large-scale permanent magnet generators with full power electronic converters are of increasing interest to many wind turbine manufacturers. These systems offer an efficient and reliable solution for offshore and low wind sites. However, the advantages of these generators necessitate a system design approach when selecting a power electronic drive and designing to meet the toughest grid code elements...
DC drives are still very important especially for low voltages and low power (e.g. in cars and robots). In this paper a Cuk-derived (one- and two-quadrant) converter is analyzed which makes it possible to control the voltage across the machine (and therefore the speed) from zero to three times of the input voltage. The model of the drive, the design of the devices, and some experimental results are...
Archimedes wave swing (AWS)-based wave energy conversion (WEC) is the first device adopting the direct-drive power takeoff. The linear permanent magnet generator (LPMG) is employed to convert the wave energy to electric power. In this paper, the power characteristics of the LPMG are discussed in detail using the model in the dq0 reference frame established by the authors in a previous work and the...
This paper presents a DSP based equipment aimed for power electronics and motor control applications that, in opposite with conventional training equipments, provides a great flexibility to design several applications. The equipment is a modular system with a DC power supply, three-phase MOS-bridge, a signal acquisition system, a DSP development kit and several loads, i.e. DC or AC motors and passive...
A new experiment for undergraduates showing voltage and frequency control of a small alternator for a two bus power system is introduced. Voltage and frequency controllers were designed in Simulink and implemented using dSPACE. A subsystem of the scaled down power system testbed developed at Florida International University was utilized to study the effects of varying load on the generator operating...
