“…PIC30F10 microcontroller was used to provide the gating signal to the unique switch for the SMR to adjust the output voltage according to the reference DC voltage, as is seen in Figure 32. In addition, the authors in [34] designed auxiliary converters for multiple functions to control the alternator's output. It consists of chargers, inverters, alternators, exciters, and converters of different voltage levels.…”

Optimization and improvement of the electrical system are applied to cope with the increased demand for electrical power in the vehicular system; they must be carried out in many ways to ensure that the vehicles are provided with the necessary electricity for their performance work electrical equipment. This paper reviews the various optimization approaches for the alternator used in automotive applications and discusses the advantages and disadvantages of each method. The optimization is achieved to the field excitation current that influences the alternator output voltage, and the other techniques designed a controller to optimize the output power of the alternator using power electronic converters. The most suitable approaches are those approaches that use real-time optimization and self-optimization methods. Combining the above two methods can achieve the best results, higher efficiency, stable performance, and a large amount of power produced by the alternator.

The auxiliary electric drive of electric locomotives is often built on the basis of three-phase induction motors. In a number of auxiliary drive circuits, direct starting of motors is practiced, which is accompanied by significant starting currents. This imposes increased requirements on the installed power of the supply converter. A method for reducing starting and operating currents through the use of three-phase capacitor banks is considered. The simulation results are presented.

“…Rectifier circuits are used in many industrial applications such as uninterruptible power supplies [1], wind turbines [2], electric vehicle charging systems [3], DC motor control [4], active filter [5], electric locomotive [6] and STATCOM [7] applications. Depending on the usage power, single-phase rectifiers are used at low power, and three-phase rectifiers are used at high power applications [8].…”

In this study, 2.5 kW single-phase pulse-width modulated rectifier is simulated with three different control techniques to investigate the performance of controllers. Rectifier simulation is performed in Matlab / Simulink environment by using hysteresis current control, sinusoidal pulse width modulation and voltage oriented control techniques. In the performance comparison of the control techniques, considering the switching frequencies, the total harmonic content of the current drawn from the grid, the phase difference between the grid voltage and the grid current, and the DC bus voltage regulation at the output are considered as comparison criteria. The switching frequency is set to 35 kHz in sinusoidal pulse width modulation and voltage oriented control techniques. Since the switching frequency is variable in the hysteresis current control technique, the average and instantaneous switching frequency are calculated for different hysteresis band values. In the results with the technique, the switching frequency varies between 18.52 kHz and 47.6 kHz, while the average switching frequency is 34.6 kHz. As a result, the total harmonic distortion of the grid current with hysteresis current control, sinusoidal pulse width modulation and voltage oriented control techniques is 3.69%, 1.12% and 1.82%, respectively. The synchronization with the grid voltage is achieved with all techniques, and the DC voltage is regulated with active power.
