Abstract
A generator or another type machine includes a controlled field alternator, a segmented waveform converter, and a controller. The controlled field alternator is configured to generate a polyphase signal. The segmented waveform converter includes multiple switches connected between the polyphase signal of the controlled field alternator and an output filter. The controller is configured to provide a control signal for the switches based on measured electrical quantities associated with the output filter and provide a field current control signal to the controlled field alternator.
