A power factor corrected (PFC) bridgeless converter–based computer power supply (CPS) using multioutput flyback dc–dc converter is presented in discontinuous conduction mode (DCM) of operation. ...
Compared to conventional buck or boost converters, this topology allows a low current ripple at the input for a relatively low level of the DC–bus voltage. The converter is used as a power factor correction (PFC) circuit for a single–phase rectifier and, based on the obtained model, steady–state analysis is performed and new design criteria were established for a ...
The converter core can be transparently embedded inside current mode power factor controller. In this paper, operation of the converter core, auxiliary circuits, and design guide lines are presented. ...
This paper presents the analysis and design of the direct power control of a boost PWM rectifier based on sliding mode control. In the aim to improve control performance of the rectifier, the proposed approach combines the merits of sliding mode control, direct power control and ...
The control laws are both elaborated on the basis of a state-space averaged model of the converter, expressed in the synchronous rotating frame. ...
First and foremost, we are the world’s most deployed large- scale distributed power solution, having sold over 700 megawatts of our solutions with power ratings over 100 kW since 2003 . ...
The simple hysteresis controller ensures the unity power factor and sinusoidal supply current. Proposed controller is designed to regulate the real and reactive power while keeping the dc bus voltage constant in BESS and SMES. Simulation is carried out using realistic power devices to study the ...
The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal utilisation of the installed wind turbine capacity. The generation system has fuzzy logic control with vector control in the inner loops. Fuzzy ...
Detailed analysis, simulation and hardware results of grid connected inverter with maximum power point tracker and power factor control in Malaysian climate are presented. ...
This paper deals with the power quality improvement of AC mains in Direct Torque-Controlled (DTC) permanent magnet synchronous motor (PMSM) drive using active wave shaping techniques. For this purpose, different topologies for active wave shaping of AC mains current in DTC-based PMSM drive such as single- and two-switch boost power ...
