A novel two-switch high-step-up isolated converter with voltage lift is proposed in this paper. The proposed isolated converter utilizes a transformer with low turn ratio to achieve high step-up gain. The secondary winding charges two boosting capacitors in parallel as switches during the switch-on period, and two boosting capacitors are discharged in series during switch-off period. Thus, the ...

Current conveyors are unity gain analog building block having high linearity, wide dynamic range and provide higher gain-bandwidth product. The current conveyors operate at low voltage supplies and consume less power. It has high input impedance, low output impedance and unity current gain (Iz/Ix=±1) as well as unity voltage gain (Vx/Vy=1). The working principle of Current Conveyors is very sim...

To provide a high votage conversion ratio, conventional non-isolated DC-DC boost topologies, which have reduced voltage capability, to operate with extremely duty cycle higher than 0.9. This paper proposes converter is mainly based on the narrow range of ratio achieve extra gain at relatively stress semiconductors. In addition, it does include any magnetic coupling structure. The structure prop...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.
