The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

A bidirectional DC/DC converter ... reduced when the same circuit module is used for buck and boost modes. The maximum current provided in both directions can be regulated, and efficiency can reach up ...

Abstract: In this article, a new bridgeless (BL) buck-boost power factor correction (PFC) converter using pulsewidth modulation (PWM) control is presented ... The proposed converter utilizes a simple ...

A high-efficiency buck ... circuit design. This is the third time that Cheng’s team has published their work in ISSCC, entitled "A 98.6%-Peak-Efficiency 1.47A/mm 2 Current-Density Buck-Boost ...

So in this article, we are going to learn how to build, and test a simplified Sepic converter built on top of the popular XL6009 IC. We have previously used this XL6009 IC to Design a Mobile Power ...

A Buck, Boost, or Buck-Boost switching regulator topology usually consists of a diode, a switching element (MOSFET) and an energy storage device (inductor/capacitor) in the power path, and a ...
