This paper presents the modelling and simulation of proton exchange membrane (PEM) fuel cell (FC) together with a dc-dc converter and dc-ac inverter. The need for the dc-dc converter arises as a result of the output voltage generated from the FC which fluctuates with variation in load. The FC voltage is therefore, controlled using dc-dc converter to provide a regulated dc voltage output at 220 V for...
A household wind generation system connected with the grid are advanced in this paper, in which a diode rectifier, a boost DC/DC converter and a single-phase inverter paralleled with the grid are utilized, and a grid-connected operation mode without power injection is adopted. A double-loop control method with a current loop and a voltage loop is applied to the inverter so that the inverter feed no...
