A new flyback DC-to -three-phase converter with sinusoidal outputs

Systematic extension of any dc-to-dc converter leads to its dc-to-three-phase equivalent characterized by sinusoidal output voltages and fast dynamic responses. This genralization principle is illustrated for the special case of the flyback topology. State-space averaging has modeled with a high degree of accuracy the performance of dc-to-dc converters. Here it is combined with the stationary-to-rotating coordinate transformation, customarily used in plyphase ac systems, to results in an effective analysis method for switched-mode dc-to-polyphase converters.
