Electric power supply system for power electric energy accumulators

Electric power supply system (up to 3-4 GW in pulse) for electromagnetic mass accelerator is considered. Unique switch units for high current (up to 1.2 MA for voltage of up to 5 kV) are described. Paper describes various designs of mass accelerators and their power supply. Considered power supply source circuit variants include: unipolar DC current generator, and multiphase synchronous generator with controlled rectifier.
