“…Taking advantage of these properties, sliding-mode control has also been applied to the design of high-efficiency buck-based dc-ac converters, where a switching dc-dc converter is forced to track, by means of an appropriate sliding-mode control action, an external sinusoidal [12]- [18]. Nevertheless, the full-bridge buck converter topology limits the ac output voltage amplitude to values lower than the dc input voltage, except in the vicinity of the output filter resonant frequency [19]. When ac amplitudes higher than the dc input voltage are required, the classical design combines a step-up turns ratio transformer and a buck converter in the dc-ac conversion circuit.…”

Abstract-This paper presents a sliding-mode control design of a boost-buck switching converter for a voltage step-up dc-ac conversion without the use of any transformer. This approach combines the step-up/step-down conversion ratio capability of the converter with the robustness properties of sliding-mode control. The proposed control strategy is based on the design of two slidingcontrol laws, one ensuring the control of a full-bridge buck converter for proper dc-ac conversion, and the other one the control a boost converter for guaranteeing a global dc-to-ac voltage step-up ratio. A set of design criteria and a complete design procedure of the sliding-control laws are derived from small-signal analysis and large-signal considerations. The experimental results presented in the paper evidence both the achievement of step-up dc-ac conversion with good accuracy and robustness in front of input voltage and load perturbations, thus validating the proposed approach.Index Terms-boost-buck switching converter, dc-ac step-up conversion, sliding-mode control.

“…For voltage fluctuation regulation during a load transient, enhanced-control methods and auxiliary converter methods are typical. Enhanced control methods, such as the V 2 control method [14]- [16], the sliding mode control method [17]- [18], and the linear-and-nonlinear control method [19]- [21], improve the load transient responses under identical hardware conditions. Nevertheless, the enhanced control methods have a limitation given the slew-rates of their output-inductor-currents.…”

This paper presents a novel control strategy for passive output filter reduction using an active output filter. The proposed method achieves the dual-function of regulating the output voltage ripple and output voltage variation during load transients. The novel control strategy allows traditional simple voltage controllers to be used, without requiring the expensive current sensors and complex controllers used in conventional approaches. The proposed method is verified with results from a 125-W forward converter.

SummaryWith the rapid growth of single‐phase renewable energy source units within three‐phase microgrids, the accuracy of the power sharing per phase among distributed generation (DG) units is necessary. This paper proposes an adaptive power control strategy based on new sliding mode control for islanding operation of a microgrid with multiple three‐phase and single‐phase DGs. The studied microgrid consists of two three‐phase photovoltaic (PV) arrays and three single‐phase DG units, which include PV, fuel cell, and battery systems. In order to control the three‐phase DGs properly, an observer is used to estimate the uncertain system parameters. Then, according to the estimated values, a controller is adapted to the new system conditions. In this control strategy, one of the three‐phase PV arrays is responsible for adjusting the voltage and frequency, and the other is responsible for controlling the load current to manage the power of three‐phase inverters. To control the single‐phase DGs, their power and voltage references are assigned based on the corresponding phase of the three‐phase DGs responsible for power and voltage control. Subsequently, the power and voltage control operation is performed in a per‐unit system. The proposed control strategy is strongly stable against variation of conditions, disturbances, and microgrid parameter uncertainties, and it regulates the active and reactive powers injected by DGs. The feasibility of the proposed control strategy is validated using simulation studies on a multibus islanded microgrid with balanced and unbalanced loading conditions via MATLAB/Simulink software. The results indicate that the proposed approach is able to provide faster response and lower steady‐state error compared with the conventional proportional integral controller.
