Control and Application of Single-phase PWM Rectifier in Aircraft Electric Systems

Abstract

This work studies the use of single-phase high power factor PWM rectifiers in aircrafts with variable frequency (360 to 800 Hz) power generation. It also presents design guidelines for input and output filters, and discusses the modeling and design of the voltage and current controllers. A 1 kW system is simulated considering a variable frequency grid, verifying the compliance with the aircraft power quality standards. Experimental results from a prototype allows to verify the design procedures.

DC bus power electronic conditioner for electric aircraft system

“…The usual topology to generate the bipolar DC bus in a aeronautic electric power system is a Transformer RectiĄer Unit (TRU) consisting of one or more diode multipulse (12 or more pulses) rectiĄers due to the harmonics restrictions, mainly the 3th, 5th and 7th harmonic components [23], [24], [25], [26], [27].…”

“…The PWM-rectiĄers are an alternative solution due to their high efficiency [30], [31], high power factor and low harmonic content [22]. Although the control system is more complex [25], [32], [33], [34] .…”
