Abstract: The conventional pulse-width modulation rectifier has the low power factor and more sensors to detect the voltage and current of alternating current side. The traditional direct power control method possesses the defect of unfixed switching frequency. A new method based on three-phase voltage source pulse-width modulation rectifier with high power factor based on direct power control ...

The performance of direct methanol fuel cell (DMFC) is closely related to its operating conditions, and there exists a specific combination of operating conditions at which the DMFC output maximum power to the driven load. Working at maximum power point (MPP) can lower the methanol crossover and ancillary power consumption so as to improve the global efficiency of the system. The fuzzy controll...

The device analyzed in this paper is Distribution STATic COMpensator (DSTATCOM). The objective is to focus on the power factor control with the two different control strategies i.e., Indirect and Direct Control Strategies. This paper presents a study about the control strategies of DSTATCOM device and their impact on the dynamic performance of distribution network. Simulation results were prese...

In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...

In this paper, a new control scheme of an active boost rectifier has been presented. Proposed power control method uses a discretetime model of the converter to predict future behaviour for all possible voltage vectors. The most effective vector is chosen for next sampling period by minimizing a cost function. Presented Predictive Direct Power Control (P-DPC) scheme has been compared with class...
