-The simulation of a nonlinear controller with power sharing control capabilities for a wind energy system double input buck boost–buck boost converter is presented. A multiple-input DC–DC converter is useful to obtain the regulated output voltage from input power source such as a wind array. Double input DC-DC buck boost converter principle of operation and the equations describing the convert...

The paper analyzes the impact of the component losses on the efficiency of the novel DC/DC converter. The converter is a combination of the quazi-Z-source (qZS) network and dual active bridge (DAB). In the analysis the mathematical loss models of the proposed DC/DC converter are derived and efficiency is estimated. Eventually the efficiency is verified experimentally.

In our paper, a method of using hybrid converter has been implemented. In the existing system, two stage approaches has been used. This two stage approach is both dc –dc converter and dc – ac Converter. This type of converters mentioned above has been used in the earlier stages, but the drawbacks that can be seen is increased cost and complexity. The proposed method mainly uses boost derived hy...

Switched Boost Inverter (SBI) is a single stage DC to AC power converter and it is derived from the Z source inverter employs an LC impedance network in between the main inverter bridge and the power source. This SBI converter can possible to supply both DC and AC loads simultaneously from a single dc input source. Here, reducing the inverter switching stress. Also, this converter provides to s...

HVDC transmission systems are becoming increasingly popular when compared to conventional AC transmission methods. HVDC voltage source converters (VSC) can offer advantages over traditional HVDC current source converter topologies; as such, it is expected that HVDC-VSCs will be further exploited with the growth of HVDC transmission. This paper presents the DC fault ride through capability and n...

The Alternate Arm Converter (AAC) is a voltage source converter being developed as an alternative to the Modular Multilevel Converter (MMC) for HVDC power transmission and reactive power compensation. Each Arm of the converter contains high voltage series IGBT Director Switches and full-bridge cells, which enables the VSC to ride through AC and DC network faults. This paper describes how the AA...
