Abstract:
Abstract Traditional three-phase four-leg inverters are widely used in microgrid systems because of their ability to carry unbalanced loads, but unbalanced load currents will cause instantaneous power to contain double-frequency fluctuations, which will affect the normal operation of the microgrid system. In order to solve the above problems, this paper proposes an improved three-phase four-leg topology and its control strategy, so that the secondary pulsating power on the load side can be provided by the decoupling capacitor. Then the working principle of the proposed topology and its control

Abstract:
In order to solve the problems of increasing the conduction loss of power devices and decreasing the conversion efficiency caused by the secondary power ripple of the single-phase pulse rectifier of high-speed trains, a buck chopper active power decoupling loop is proposed to replace the LC filter loop, which absorbs the secondary pulsation power by increasing the pulsation of the energy storage capacitor and reduces the capacity of the energy storage capacitor to improve the power density of the system. It integrates and improved deadbeat-repetitive control without difference, improves the in

Abstract:
Due to fewer conduction devices in operating condition, the bridgeless power factor correction (PFC) converter is more efficient than the traditional PFC circuit. However, to achieve a low output voltage ripple on the DC side, a large electrolytic capacitor must be connected in parallel to the output end. To reduce the value of capacitance, this paper proposes a dual-boost bridgeless PFC converter with a bidirectional buck/boost power decoupling converter in the latter stage. The bidirectional converter absorbs double-line-frequency ripple, lowering the power pulsation at the output end while

This paper presents an improved topology for three-phase to single-phase matrix converter (3-1 MC), and discusses the power decoupling method, closed-loop control strategy, etc. These studies make the single-output MC have good features, such as sinusoidal input current, low total harmonic distortion (THD), compensating the shortcomings of traditional 3-1 MC caused by the output power pulsation. According to the improved scheme, a novel closed-loop control strategy based on virtual dc voltage feedback is proposed. The strategy completes the closed-loop control of 3-1 MC by taking the virtual d

Abstract:
Due to the inherent frequency ripple in single-phase photovoltaic (PV) grid-connected solar inverters, the Maximum Power Point Tracking (MPPT) will inevitably be affected. To improve the MPPT performances, a passive LC power decoupling circuit with a Robust Sliding-Mode Control (RSMC) is proposed in this article. The frequency pulsation on the DC link is effectively canceled with the passive LC decoupling path. Thus, the MPPT accuracy is significantly enhanced, and the utilization of a small DC-link capacitor becomes possible. The resonance between the LC circuit and the main DC-link capacitor

L’élément clé du système de conversion de puissance est le convertisseur statique connecté au réseau. Pour les applications de faible puissance, le convertisseur monophasé est le meilleur compromis. Les structures de conversion mono-étage permettent d’avoir un rendement plus élevé ainsi qu'un coût et une taille réduits.

Abstract In this work, a hydraulic state of the art injection molding machine is retrofitted with a dual pump drive. The dual pump drive is an electro-hydraulic speed-variable drive, with focus on high bandwidth control through secondary control principles. Secondary control is based on providing the torque references for the electric machines directly, instead of a speed reference. The pressure control loop is based on decoupling of the piston load pressure and sum pressure enabling the possibility to utilize two SISO controllers. The application is the injection cylinder of an industrial inj
