Abstract
This paper deals with the design, control, and implementation of a three-phase ac–ac mobile utility power supply using a matrix converter for airplane servicing applications. Using a matrix converter as a compact direct ac-to-ac converter can provide savings in terms of the size and cost of a mobile power supply compared to common back-to-back converters. Furthermore, using the proposed direct matrix converter eliminates the need for bulky electrolytic capacitors and increases the system’s reliability and lifetime. A finite control set model predictive control is used to generate a high-quality 115 V/400 Hz output voltage and a low-harmonic-distortion source current with a unity input power factor for various load conditions, including balanced, unbalanced, linear, and nonlinear loads. The predictive strategy is used to control the output voltage and source current for each possible switching state in order to simultaneously track the references. To achieve a further reduction in the system’s size and cost, an active damping strategy is used to compensate for the instability caused by the input filter in contrast to the passive method. Experimental tests were conducted on a prototype matrix converter to validate the performance of the proposed control strategy.
Highlights
In recent years, power-electronics-based power supplies coupled with an output LC filter have been proposed for different applications
This paper presents the design of an FCS-model predictive control (MPC) for a three-phase ground power units (GPUs) based on a direct matrix converter
The control schemes were implemented in C code by using a digital signal processor (DSP; model TMS320F28335), and a field-programmable gate array (FPGA) on a Xilinx Spartan6LX150T development board was programmed in VHDL to realize a fourstep current-based commutation process [41]
Summary
Power-electronics-based power supplies coupled with an output LC filter have been proposed for different applications. Ground power units (GPUs) provide balanced and sinusoidal phase-to-neutral voltages of 115 Vrms at a frequency of 400 Hz to supply airplanes with external electrical power during stopovers in airports. Because of the low ratio between the switching frequency of the converter and the fundamental output frequency (400 Hz), only some special control methods can achieve the requirements of the GPUs. Back-to-back converters have been conventionally used to provide power as GPUs for aircraft, where a dc filter reduces the current ripple of the rectifier and supplies the inverter. The control of inverters with an output LC filter can achieve good voltage regulation with different kinds of loads [1,2,3]. Instead of back-to-back converters, matrix converters (MCs) can be utilized
