DC-DC converters have been applied to industrial applications widely during the past few decades. With rapid development of technology, negative output (N/O) dc-dc converters play an important role in the industrial fields, such as regenerative braking system (RBS) of DC motors for hybrid electric vehicles, signal generator and data transmission interface, neutral point clamping power electroni...

In this paper a single-inductor dual-output (SIDO) buck-boost PFC converter operating in critical conduction mode (CRM) is proposed. By multiplexing a single inductor, each output of SIDO buck-boost converter can be regulated independently. Compared with conventional two-stage multiple output converter, SIDO buck-boost PFC converter benefits from significant overall cost saving, small size and ...

In this paper, a two-stage AC/DC converter is presented for a low-profile laptop adaptor. The system consists of a boost power factor pre-regulator and LLC resonant converter. The pre-regulator features high PF and high-efficiency, while secondary LLC converter features zero voltage switching (ZVS). The transformer in LLC converter is splited in two to reduce current stress and converter height...

This paper deals with the simulation of closed loop and open loop controlled Interleaved Boost Converter (ILBC). It is seen that, for higher power applications, more modules can be paralleled to increase the power rating and the dynamic performance. One of the challenge in designing a boost converter for high power application is how to handle the high current at the input side. In this paper a...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

this paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (apf), based on flying capacitor multicell (fcm) converter. increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of fcm converter compared with conventional multi...

Single phase power factor correction ac-dc converters are widely used in industry for ac-dc power conversion from single phase ac mains to an required output dc voltage. In case of high power application these types of converter use an ac-dc boost converter followed by dc-dc converter. These converters has the features of excellent input power factor, continuous input and output currents, and i...

A log-domain current-mode true RMS-to-DC converter based on a novel synthesis of a simplified current-mode low pass filter and a two-quadrant squarer/divider is presented. The circuit employs floating gate MOS (FG-MOS) transistors operating in weak inversion region. The converter features low power(

In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. ...
