An Active Power Factor Correction Technology for Aircraft

Ac 2011-1479: an Active Power Factor Correction Labora- Tory Experiment for Power Electronics Course

The use of power factor correction (PFC) circuits has been proven to save electrical energy use by up to 25%. When electrical loads are predominantly linear, a simple shunt capacitor will generally be sufficient to improve the power factor. However, as the use of power electronics becomes more prevalent, a more advanced solution using active components is needed. One such active PFC circuit cur...

Novel Auxiliary Power Unit Configuration Based On Fuel Cell Technology for Civil Aircraft Application

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...

An All-Electric-Aircraft Tailored SiC-Based Power Factor Correction Converter with Adaptive DC-Link Regulator

In recent years the aerospace industry has made a growing effort to develop a quieter and more environmentally friendly aircraft. In particular, several research activities have been focused on innovative solutions aimed at the design/optimization of an on-board electric system fully compatible with this new approach.

Three Phase Active Power Factor Correction in a Single Step

Simulation of Active Power Factor Correction Using Boost Type Converter

With the vast development in the usage of Power electronic devices like Rectifiers (nonlinear loads) the current drawn from the line is distorted resulting in a High Total Harmonic Distortion (THD) and Low Power Factor (PF). Hence there is a continuous need for Power factor improvement and reduction of line current harmonics. The most popular topology for Active PFC is a boost converter as it d...
