A Double input DC to DC converter for low voltage energy sources applications is proposed in this paper. The proposed converter is buck-boost converter which can step up or step down the input voltage according to output voltage required at load end. The converter is able to boost up voltage of energy sources such as solar photovoltaic and wind energy system of relatively low voltage. The conve...

In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

A novel bidirectional DC-DC converter is presented in this paper. The circuit configuration of the proposed converter is very simple. The proposed converter employs a coupled inductor with same winding turns in the primary and secondary sides. In step-up mode, the primary and secondary windings of the coupled inductor are operated in parallel-charge and series-discharge to achieve high step-up ...

This paper presents the three phase AC/DC converter drive effects on the linearity of the Torque-speed characteristics. A MATLAB/Simulink realization of the three phase AC/DC converter drive is described. The DC motor speed control is achieved by controlling the voltage applied to the armature circuit using three phase AC/DC converter drive. A comparison between the application of three phase s...

In this paper, a bidirectional AC DC converter is analyzed. The converter applies a half bridge thyristor rectifier and a recuperating thyristor bridge instead of a braking resistor. Recuperating mode of the converter is focused in the analysis, and it is shown that the converter exposes two operating modes within the recuperating mode, one characterized by negligible, and the other one charact...
