Abstract-Existing control schemes for a single-phase ac-to-dc converter with active powerdecoupling function typically involve a dedicated power-decoupling controller. However, due to the highly coupled and nonlinear nature of the single-phase system, the design of the power-decoupling controller based on the conventional linear control techniques is cumbersome, and the control structure is complicated. Additionally, with the power-decoupling control, it is generally difficult to achieve satisfied dynamic responses and robust circuit operation. Following a recently proposed automatic-power-decoupling control scheme, this paper proposes a nonlinear control method that can achieve enhanced dynamic responses and strong disturbance rejection performance without the need for a dedicated power-decoupling controller. The proposed controller has a simple structure, of which the design is straightforward. In addition, the control method is generally applicable to single-phase ac-to-dc systems with active power-decoupling function. Simulation and experimental results validate the feasibility of the proposed control method on a two-switch buck-boost PFC rectifier prototype.Index Terms-Automatic power decoupling control, single-phase ac-to-dc converters, power decoupling.

Abstract:The Phase Locked Loop (PLL) technique has been studied to obtain the phase and frequency information in grid-connected distributed generations for the sake of synchronizing the grid voltage and the inverter output current. In particular, the line frequency information, such as the anti-islanding function, is very important for the grid connection requirement. This paper presents a novel frequency measurement method from the digital PLL control structure for single-phase grid-connected PV applications. The conventional PLL controller uses the phase information to calculate the frequency of PV inverter output voltage after every line cycle and has shown a relatively low accuracy. This paper uses the angular frequency to directly measure the frequency after every line cycle. To verify the validity of the proposed method compared with the conventional method, a simulation was conducted. According to the simulation results, the measurement error of the proposed method is 80 times lower than the conventional one.

“…According to this figure, the power conditioning system includes two stages: a bi-directional AC/DC converter and a bi-directional DC/DC converter. The bi-directional AC/DC converter is usually a single-phase active rectifier and the bidirectional DC/DC converter is commonly an isolated dual active bridge converter [41]- [42]. There is an LCL-filter at the input of the active rectifier used in order to eliminate the high frequency harmonics [43].…”

“…The two external control loops are the active power control loop and the reactive power control loop. The active power control loop usually regulates the DC-bus voltage in order to balance the active power flow [41]. This loop basically determines the amplitude of the current component aligned with the grid voltage.…”

This paper presents a new active/reactive power closed-loop control system for a hybrid renewable energy generation system used for single-phase residential/commercial applications. The proposed active/reactive control method includes a hybrid estimator, which is able to quickly and accurately estimate the active/reactive power values. The proposed control system enables the hybrid renewable energy generation system to be able to perform real-time grid interconnection services such as active voltage regulation, active power control, and fault ride-through. Simulation and experimental results demonstrate the superior performance of the proposed closed-loop control system.
