In this paper, a new embedded Z-H (EZ-H) buck-boost converter is proposed. In this topology, two identical dc voltage sources are embedded in a LC network in a series connection with the inductors. The proposed converter eliminates the shoot-through (ST) switching state and there is no need for a front-end diode. Other advantages of the proposed topology are having capability of buck and boost ...

The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains providing high power factor and good efficiency. And with a careful design of the converter the filter capacitances can be made small enough so that film capacitors may be used. Thus the converter mean time between failures can be made as high as that of the solid-sta...

A DC–DC switching converter chip is proposed to generate both positive and negative voltages for active-matrix LCD (AMLCD) bias. An inductive boost converter and two inverting charge pumps are integrated in a proposed chip by using a 0.5 mm 5 V, 3.5 mm 30 V CMOS process. A conventional scheme used to bias AMLCD employs a switching-boost converter with several off-chip components to generate the...

High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

Due to increasing concerns on the power quality, power factor correction (PFC) has become an important issue in light-emitting diode (LED) lighting applications. A boost converter is one of the most well-known PFC topologies, due to its simple circuitry, simple control scheme and small number of passive components. Even though a boost converter is recognized as a typical PFC converter, its outp...
