ABSTRACT:
A high-voltage DC transmission system and method is characterized by a minimum filtering requirement as to ripple as well as to surge and harmonics. Use of a superconducting generator directly coupled to rectifying means eliminates the requirement of a step-up transformer and allows operation at high frequency for minimizing ripple (and related filtering).
