“…Figure 7 shows the simulation for ordinary PWM technic. Wind speed affects the output power from the PMSG which is connected to WT [20], that means with no excitation system the output voltage will change due to wind speed and load value, the AC voltage from PMSG will be rectified in the first stage from the converter, and will become the input for the inverter phase, Figure 8 shows the DC voltage during the simulation time.…”

Power quality (PQ) problems for renewable energy system (RES) is major challenge for using these systems. Amplitude, frequency, and waveform is important PQ parameters especially for standalone or isolated systems. In this paper we propose RES with wind turbine (WT) and permanent magnet synchronous generator (PMSG) to feed different loads (liner, non-liner) through AC-DC-AC converter. The PMSG operate with fuzzy logic inertia controller, to convert turbine torque form PU to Nm. The inverter stage in the converter operate according to proportional integral derivative (PID) controller with 3rd harmonic injection pulse width modulation (PWM) to regulate the AC voltage in load side. For the same case study and operating condition, we compared the result for system parameters when using ordinary PWM and using PID with 3rd harmonic injection. Voltages total harmonics distortion (THD) was less than 2% with liner loads, and 3.5% with non-liner load and the same was for current load, the voltage amplitude was between (1-1.03) PU under different wind speed by using the proposed controller.

“…For that matter, the purpose of the second stage is closer to the post-regulator or third stage of the single-phase ac-dc multi-stage scheme. The topologies normally used for the second stage are similarly based on the ones introduced for the single-phase multi-stage LED drivers due to the requirement of a high step-down gain [223], [224] (i.e., LLC or AHB).…”

Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density. Some of these advantages will make LED light sources to be more than just a lightbulb, being able to transmit data, control light color, hue and intensity or even detect people in indoor environments. Nevertheless, these advantages attributed to LED capabilities are, in reality, achieved thanks to the LED driver. The present work reviews the current stateof-the-art strategies to drive LEDs from ac power grids with special emphasis into removing the most limiting component from the point of view of the lifetime, which is the electrolytic capacitor, while achieving a flicker-free performance of the light output of the LED driver. Moreover, it focuses on analyzing the required regulations, challenges and applicability of LED drivers in both single-phase and three-phase ac power grids.Note: This only applies for certified dimmable luminaires.

“…Azazi, H.Z presents a single-stage, three-phase power factor correction (PFC) rectifier using a single-switch boost regulator with less than 5% total harmonic distortion (THD) in the supply current [6]. A three-phase, single-stage AC-DC converter with topology utilizing SiC MOSFETs is proposed and analyzed by Zhang, Z [7]. Compared with DCM mode operating in other single-stage converters, continuous current mode (CCM) mode is working in the proposed converter, which reduces the current stress running through the semiconductor devices.…”

An active clamp, three-phase, six-switch power factor correction rectifier with a one-cycle controller is proposed, which can effectively suppress the reverse recovery of the reverse parallel diode of the bridge arm switch and reduce the reverse recovery loss. The main switches and auxiliary switch are both zero-voltage switches. It works in a fixed switching frequency and low power stress during the switching period. The specific working process and control circuit are analyzed in detail, and the model simulation is carried out. The experimental platform of a 2.5 KW prototype, with a complete test and verification of the soft switch technology proposed in this paper, was set up in the laboratory.
