Average current control for aircraft applications

Five, single-phase H-bridge converters are used to interface variable-speed, permanent magnet generator into a common DC bus. To draw high quality current from the generator and provide constant DC voltage, a modified implementation of the average current control technique is proposed. A phase shift circuit was added to the average current control to allow system operation at different load and speed conditions. The proposed technique has a significantly faster dynamic performance. The analysis was validated using rigorous simulation.
