Analysis of prospective aviation power supply system with multiphase generator and stabilized rectifier

The questions of new generation electrical equipment design for future power supply systems, which may be required on the board of unmanned aerial vehicles, helicopters, training aircraft are discusses in this paper. The topology of DC power supply channel with specialized alternators are proposed. The ways to reduce weight and improve the reliability of the rectifying devices are discusses. The scheme of controlled multipulse rectifier based on a single winding saturation inductor is proposed. The results of the weight, size and energy calculations of the proposed rectifier topology at input voltage source frequency variation are presented. The simulation results of proposed 18-pulse rectifier model are given in transient modes at variations of the load current and power supply voltage.
