Multilevel inverters are used in high power and medium voltage applications. Employing multilevel inverter with renewable energy alone, the voltage balance cannot be made because the number of level increases in multilevel inverter the control gets complexity. So voltage imbalance problems are introduced. The voltage imbalance problems can be classified into two types; Midpoint unbalance and th...

The paper deals with active filter design with new type of active elements called voltage conveyors. Principal characteristics of voltage conveyors are described and various types are classified.

A novel high step-up dc–dc converter for fuel cell energy conversion is presented in this paper. The proposed converter utilizes a multiwinding coupled inductor and a voltage doubler to achieve high step-up voltage gain. The voltage on the active switch is clamped, and the energy stored in the leakage inductor is recycled. Therefore, the voltage stress on the active switch is reduced, and the c...

Low power, high-speed bus architectures, based on low swing voltage technique, using multithreshold voltage transistors are proposed in this paper. Three different classes of driver/repeater/receiver circuits are introduced. The driver circuits are comprised of high threshold voltage MOSFET transistors, in order to reduce their output swing level voltage. For re-pulling up the low swing voltage...

In this paper, a high step-down interleaved buck coupled-inductor converter (IBCC) with active-clamp circuits for wind energy conversion has been studied. In high step-down voltage applications, an IBCC can extend duty ratio and reduce voltage stresses on active switches. In order to reduce switching losses of active switches to improve conversion efficiency, a IBCC with soft-switching techniqu...
