For Project Title


Project Zone > Electrical > Power Electronics

An integrated high-power-factor converter with ZVS transition

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW01


Project Desc : This paper proposes a single-phase high-power factor ac/dc converter with soft-switching characteristic. The circuit topology is derived by integrating a boost converter and a buck converter. The boost converter performs the function of power-factor correction (PFC) to obtain high power factor and low current harmonics at the input line.

Request Synopsis

High-frequency-fed unity power-factor AC-DC power converter with one switching per cycle

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW02


Project Desc : This paper presents a power converter and its control circuit for high-frequency-fed ac to dc conversion. Based on the resonant technique, the input current is shaped to be sinusoidal and is forced to follow the high-frequency sinusoidal input voltage so as to achieve unity power factor.

High-power-factor rectifier using the modified sepic converter operating in discontinuous conduction mode

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW03


Project Desc : The theoretical and experimental analysis of a modified version of the SEPIC dc-dc converter used as preregulator operating in discontinuous conduction mode (DCM) is presented in this paper.

Request Synopsis

Improved-power-quality bridgeless-converter-based multiple-output SMPS

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW04


Project Desc : This paper deals with the design, analysis, simulation, and development of a power-factor-correction (PFC) multiple output switched-mode power supply (SMPS) using a bridgeless buck-boost converter at the front end. Single-phase ac supply is fed to a pair of back-to-back-connected buck-boost converters to eliminate the diode bridge rectifier.

Request Synopsis

Power factor corrected zeta converter based improved power quality switched mode power supply

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW05


Project Desc : Multiple output Switched Mode Power Supplies (SMPSs) for personal computers (PCs) normally depict extremely bad power quality indices at the utility interface such as total harmonic distortion of the input current being more than 80%, power factor being lower than 0.5 and output voltage regulation being very poor.

Request Synopsis

Single-inductor dual-output buck-boost power factor correction converter

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW06


Project Desc : A single-inductor dual-output (SIDO) buck-boost power factor correction (PFC) converter operating in critical conduction mode is proposed in this paper. By multiplexing a single inductor, each output of the SIDO buck-boost converter can be regulated independently.

Request Synopsis

A novel three-phase buck-boost AC-DC converter

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW07


Project Desc : A simple, low-cost, reduced-switch, three-phase ac-dc buck-boost converter is proposed in this paper. The converter can operate with input power factor correction and is suitable for applications where a converter needs to operate over a wide range of input ac voltages and/or produce a wide range of output dc voltages.

Request Synopsis

A fast-converging MPPT technique for photovoltaic system under fast-varying solar irradiation and load resistance

Category : Power Electronics


Sub Category : DC TO DC CONVERTERS (CHOPPERS)


Project Code : ITPW08


Project Desc : Under fast-varying solar irradiation and load resistance, a fast-converging maximum power point tracking (MPPT) system is required to ensure the photovoltaic (PV) system response rapidly with minimum power losses. Traditionally, maximum power point (MPP) locus was used to provide such a fast response.

Request Synopsis

A high gain input-parallel output-series DC/DC converter with dual coupled inductors

Category : Power Electronics


Sub Category : DC TO DC CONVERTERS (CHOPPERS)


Project Code : ITPW09


Project Desc : This paper presents a novel input-parallel output-series boost converter with dual coupled inductors and a voltage multiplier module. On the one hand, the primary windings of two coupled inductors are connected in parallel to share the input current and reduce the current ripple at the input.

Request Synopsis

High gain zero voltage switching bidirectional converter with reduced number of switches

Category : Power Electronics


Sub Category : DC TO DC CONVERTERS (CHOPPERS)


Project Code : ITPW10


Project Desc : The proposed bidirectional converter operates under zero voltage switching (ZVS) condition and provides large voltage diversity in both the modes of operation. This enables the circuit to step up the low battery bank voltage to high DC link voltage and vice versa.
