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.
