“…The active power decoupling topologies can be divided into two main categories. In the first category, the main power converter (dc/ac or ac/dc) and active power decoupling circuit (auxiliary circuit) operate independently [7]. In the second category, however, the active power decoupling circuit shares some or all switches with the main power converter [8].…”

This paper proposes grid voltage sensorless model predictive control for a single-phase T-type rectifier with an active power decoupling circuit. The proposed sensorless technique is based on a model reference adaptive system (MRAS) and tested under distorted grid conditions. This study also examines the relationship among the ripple energy, the dc-link capacitor, and the active power decoupling circuit capacitor. The developed control technique is proposed to ensure the following objectives; (1) sensorless grid voltage estimation; (2) the second-order ripple power elimination; (3) reference current generation based on power equilibrium; (4) ensuring unity power factor under all operating conditions; and (5) capacitor voltage balance. The developed control structure offers simplicity and it is cost-effective due to the absence of a grid voltage sensor. An experimental prototype is established, and the main results, including the steady-state and dynamic performances, are presented to validate the effectiveness of the proposed control. INDEX TERMS Sensorless control, model predictive control, active power decoupling, single-phase PWM rectifiers.

“…Although, these technologies can effectively reduce low frequency ripple without adding supplementary components, due to the complexity of the voltage controller bandwidth setting and obvious overshoot, it is difficult to completely eliminate the low frequency ripple during load transients. To address this problem, reference [25] proposed an instantaneous ripple power control method based on model predictive control. It overcomes the disadvantage of poor dynamic performance during load transients.…”

The fuel cell grid-tied power generation system usually includes a dc-dc converter and a dc-ac inverter. In a singlephase system, inherent low-order current pulsations are introduced into the system, which can have harmful effects on the fuel cell stack. For example, reducing the output voltage and output efficiency, a reduction in service life, and even accelerates the degradation rate of the membrane electrode of a proton exchange membrane fuel cell (PEMFC). In addition, dc/ac coupling power can cause distortion in the dc input current and ac grid current. To eliminate the input ripple and ensure high ac power quality on the grid side, this paper proposes a novel power decoupling control for single-phase grid-tied PEMFC systems, which uses an improved model predictive control (MPC) algorithm. With the help of the virtual vector methods, which are realized by a twostage optimization method, excellent tracking effect and robustness can be ensured. Simulations and experimental results show that the proposed algorithm can not only completely eliminate the input current ripple and reduce the total harmonic distortion (THD) of ac current on the grid side, but also improve the transient performance of the system.INDEX TERMS fuel cell, low frequency current ripple, model predictive control, ripple elimination.

“…The active power filter (APF) can divert and store the doubleline frequency power pulsation by using much smaller energy storage components. There are different APF circuit topologies depending on the location of the APF and the type of components used for energy storage in the APF [13,[19][20][21][22][23][24][25][26][27][28][29][30]. The APF can be implemented at the DC side [24,25,27] as shown in Fig.…”

This paper proposes a voltage-source converter for an on-board Electric Vehicle (EV) charger which is compatible with both the single-and three-phase (1-ϕ and 3-ϕ) grids. The classic 3ϕ active AC-DC rectifier circuit is used for both the 1-ϕ and 3-ϕ connection, but a new control scheme and LCL filter are designed to address the double-line frequency power pulsation issue caused by a 1-ϕ grid without using bulky DC capacitors. The third leg of the circuit is utilized to control the power pulsation in conjunction with stored energy in the LCL filter between the grid and charger rectifier. Neither additional active nor passive components are required. For the 3-ϕ connection, the rectifier is under balanced operation; when connected with the 1-ϕ grid, all three legs are controlled cooperatively as a 3-ϕ rectifier but under unbalanced operation to recreate the 1-ϕ voltage. Hence advantages from the 3-ϕ rectifier such as space vector pulse width modulation (SVPWM) and Y/Δ transformation can be utilized to increase utilization of DC-link voltage and filter capacitance respectively. The operation principle, control, and LCL filter design are reported and validated by both simulation and experiments of a 3-kW porotype.Index Terms-1-ϕ and 3-ϕ compatible rectifier, EV battery onboard charger, double-line frequency power pulsation, power decoupling. 1
