A single-phase buck-boost type AC-DC power converter with a sliding mode derived control strategy and using only two switches is presented and discussed. To achieve sinusoidal input current and high power factor, sliding mode control of the input current is proposed. A proportional integral (PI...
In this paper, a new two-switch zero current switching (ZCS) bridgeless boost rectifier with high power factor (PF) is proposed. The proposed bridgeless converter is based on a totem-pole configuration which allows the current to flow from high side to low side and vice versa during resonance...
The converter is running at 400kHz; the input voltage is 12V and output voltage is 1.2V with a maximum-rated current of 50A. This converter delivers up to 40A at +70°C with as little as 200 LFM of airflow.Figure 1. Schematic of a two-phase buck converter with a coupled choke. Not...

Integrated Double Buck–Boost Converter as a High-Power-Factor Driver for Power-LED Lamps 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...
The four-switch buck-boost (FSBB) converter has received widespread attention due to its simple structure, flexible control and state switchability. However, the traditional control strategy makes it difficult to meet the requirements of high performance, high stability and high security at the same...
I. INTRODUCTION HE two-switch buck-boost (TSBB) converter, as shown in Fig. 1, is a simpli?ed cascade connection of buck and boost converters [1]. Compared with the basic converters, which have the ability of both voltage step-up and step-down, such as inverting buck-boost, Cuk, ...
AN_2108_PL88_2108_231056 XDPP1100 two-phase interleaved buck-boost -48 V to 28 V 780 W digital power supply About this document Scope and purpose The non-isolated -48 V to 28 V inverted buck-boost converter is often used in the telecom base st...
Rev. C | Page 17 of 32 ADP1850 INPUT CAPACITOR SELECTION The input current to a buck converter is a pulse waveform. It is zero when the high-side switch is off and approximately equal to the load current when it is on. The input capacitor carries the input ripple current, allowing the...
