In this study, we propose a novel pulse-width modulation (PWM) method to reduces common-mode noise. The proposed includes 120-degree dormant two-phase modulated three-phase inverter that the comparative carrier of one two phases. This configuration is easy implement because it uses triangular-wave comparison. an experiment using inverter, current was reduced by approximately 60%, and in particu...

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, an optimal adaptive fuzzy integral sliding mode control is presented to control the robot manipulator position tracking in the presence of uncertainties and permanent magnet dc motor. in the proposed control, sliding surface of the sliding mode control is defined according to the information of position tracking error, derivatives, and error integral. in order to estimate bounds ...

Fuel cell powered systems have low voltage and high current output characteristics. Therefore, the output voltage of the fuel cell must be stepped up by DC-DC converter. In this paper an integrated mathematical model for proton exchange membrane fuel cell power system with DC-DC converter is described by analyzing the working mechanism of the proton exchange membrane fuel cell and the boost DC-...

Both Soft computing based controllers and sliding mode controllers have been utilized to regulate the output voltage of dc-dc converters in response to changes in the load and the input voltage. Although both control techniques possess desirable characteristics, they have disadvantages which prevent them from being applied extensively. Many researchers have proposed the combination of sliding m...

decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. in this paper, a new droop control s...

recently, special type of fuel cells has been developed that operates in a dead end mode. working in this condition, the dead-end fuel cell is supplied withhydrogen almost at the same rate of consumption. it is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.water accumulation that is directly proportional to the cell current is of a great...

in this paper, a two-surfaces sliding mode controller (tssmc) is proposed for the voltage tracking control of a two input dc-dc converter in application of electric vehicles (evs). the imperialist competitive algorithm (ica) is used for tuning tssmc parameters. the proposed controller significantly improves the transient response and disturbance rejection of the two input converters while prese...
