Abstract
A simple, per-phase controller is described for a five-phase, fault-tolerant, permanent magnet generator. The power conditioning and control system for the generator comprises five independent H-bridge converters operating with sinusoidal PWM and supplying a common high-voltage dc bus. The separate controllers adjust the PWM pattern in each converter to regulate the dc bus voltage over the 3:1 machine speed range, which requires field weakening operation at high speed. Small-signal analysis is used to form a theoretical basis for the control loop design. Practical results are included from a 70 kW, five-phase prototype system to validate the analysis and illustrate the controller performance. © 2008 IEEE.
