English abstract:
In the course of the More Electric Aircraft program
frequently active three-phase rectifiers in the power range of
several kilowatts are required. It is shown that the three-phase
delta-switch rectifier (comprising three delta-connected bidirectional
switches) is well suited for this application. The system is analyzed
using space vector calculus and a novel PWM current controller
modulation concept is presented, where all three phases are controlled
simultaneously; the analysis shows that the proposed concept
yields optimal switching sequences. Analytical relationships
for calculating the power components average and rms current
ratings are derived to facilitate the rectifier design. A laboratory
prototype with an output power of 5 kW is built and measurements
taken from this prototype confirm the operation of the proposed
current controller. Finally, initial EMI-measurements of the system
are also presented.
