Abstract

This paper presents a unified control method for the combined permanent magnet generator (PMG) and three-phase boost rectifier that can be used in autonomous power systems such as more-electric aircraft requiring high power density. With the unified control, the paper shows the system can function well without additional boost inductors. The design procedure for the control is presented, including current loops, voltage loop, reactive power loop and rotor position estimator loop. Simulation and experimental results show that both the DC link voltage and reactive power could be controlled effectively. In addition, the paper proposes a method to optimize the overall system efficiency by appropriate reactive power distribution. The power density and efficiency of the PMG and rectifier system is improved with the unified control.
