“…A full‐wave bridge with centre tapped secondary was proposed in [11] to control the rectifying process, but the switching loss is increased because of two switches in an active rectifier are involved at each transition. The variation in the HFLMR topology to use a pure capacitive output filter has been proposed in [12, 13]. The rectifier diode voltage can be clamped by doing so.…”

A high-frequency link matrix rectifier with a pure capacitive output filter has the advantages of reduced converter size and clamped voltage over the rectifier diode. However, when the converter operates in discontinuous conduction mode (DCM), there is high input current distortion. The distortion has to be compensated such that the total harmonic distortion (THD) does not exceed 5%. The straightforward way of reducing distortion is by designing the switching scheme. In this study, switching schemes based on space vector modulation have been studied to improve the input current quality in DCM. Several existing switching schemes and newly proposed switching schemes have been analysed and compared. A 600 W laboratory prototype has been built to verify the effect of switching schemes over input current quality. The experimental results show that the input current THD can be greatly reduced by applying proper switching scheme.

“…DAB-based single-stage three-phase converters have been discussed in [25]- [26][27] [28], where [25] supports unidirectional power flow. A single-stage reduced switch count converter is proposed in [26], where the ac-ac converter on primary is realized using a push-pull structure.…”

In vehicle-to-grid applications, the battery charger of the electric vehicle (EV) needs to have a bidirectional power flow capability. Galvanic isolation is necessary for safety. An ac-dc bidirectional power converter with high-frequency isolation results in high power density, a key requirement for an on-board charger of an EV. Dual-active-bridge (DAB) converters are preferred in medium power and high voltage isolated dc-dc converters due to high power density and better efficiency. This paper presents a DAB-based three-phase ac-dc isolated converter with a novel modulation strategy that results in: 1) single-stage power conversion with no electrolytic capacitor, improving the reliability and power density; 2) open-loop power factor correction; 3) soft-switching of all semiconductor devices; and 4) a simple linear relationship between the control variable and the transferred active power. This paper presents a detailed analysis of the proposed operation, along with simulation results and experimental verification.

“…This fuzzy logic behavior is good for tremendous intelligent control technique when compare to digital logic. The fuzzy logic consist of fuzzy controller and fuzzy sliding mode controller, these controller are robust [3][4][5]. Even though these are in robust, it has some drawbacks related to control parameter selection constraints and complex theory.…”

This paper presents harnessing of maximum wind energy from natural resource whenever it's available. The power electronic converters role is important In between sources and load. The load may be linear and non-linear in nature, so converters performance decides the efficiency of the system. Proper controller can switch the converter in the desired time and improve the system performance and stability. Many controllers are suggests to control the converter to get better performance in at output side. The proposed system also has boost converter, bidirectional DC-DC converter and inverter for grid and wind energy integration. The boost inverter/buck rectifier in this system is controlled by ANFIS controller is for better output, boost and bidirectional DC-DC converters are controlled by PID controller in closed loop. Overall operations are based on modes main controller speedgoat, which is control the system operation in different modes. Any variation happening in the input, storage and load parameters speedgoat changing the mode and operate the system is in effective way. Based on the system conditions speedgoat generates control signal for the control breakers, these control breakers changing modes of operation. ANFIS, PID and speedgoat are the three controllers combined together which harness maximum wind energy and this system is applicable for both linear and non-linear loads in domestic applications.
