In this paper, a new type of interleaved high step-up converter including coupled inductor is proposed. The proposed has an configuration on the input side to reduce ripple current and increase power level. Moreover, stacked structure output provides input/output (I/O) voltage gain. addition, can avoid extreme duty cycle, causing larger conduction losses, by combining lossless clamp circuit wit...

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...
