Abstract: Four-switch synchronous buck-boost (FSBB) converter is much suitable for battery management system for its characteristic of wide input voltage range, high efficiency, and positive voltage output. A three mode control scheme with two modulation signals and one carrier can be adopted to achieve the smooth transition among modes. Using feed forward voltage mode control, the input voltag...
On remote islands photovoltaic (PV) panels with battery energy storage systems (BESSs) supply electric power to customers in parallel operation with engine generators (EGs) to reduce fuel consumption and environmental burden. A BESS operates in voltage control mode when it supplies power to loads alone, while it operates in current control mode when it supplies power to loads in parallel with t...
The paper presents the design of discrete-time quasi-sliding mode voltage controller for DC-DC buck converter. The control algorithm is realized by measuring only sensed output voltage. No current measurements and time derivatives of output voltage are necessary. The proposed quasi-sliding mode controller provides stable output voltage, exhibiting robustness to parameter and load variations.
in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...
The main goal of this research is to design a new digital controller for a boost-switching converter in Continuous Conduction Mode (CCM), which operates in Voltage Mode Control (VMC). Boost converter transfer function in the mentioned modes have one Right Half Plane (RHP) zero and a pair of complex poles while their places are severely dependent on input voltage, reference voltage and converter...
Voltage sag is a serious power quality problem affecting domestic, industrial and commercial customers. Voltage sags may either decrease or increase in the magnitude of system voltage due to faults or change in loads. In this paper a switch mode AC BuckBoost regulator is proposed to maintain voltage across a medium size domestic appliance constant during long period of voltage deviation from th...
This paper discusses the design and simulation of Slope compensated Current mode Controlled Boost converter which is used in several applications like regulated switch mode dc-dc power supplies. There are several types of dc-dc converters. A boost converter simply steps up a source voltage to a higher, regulated voltage. This allows one power supply to provide different voltage levels at differ...
In this paper, a multi-stage Z-source inverter with high boost factor is proposed. The proposed topology by using the combination of a power supply and Z-source networks are increased the voltage. Regarding voltage increase capability over the wide range, good resistance against electromagnetic noise and immunities against shoot through (ST), this inverter can be used widely in the photovoltaic...
