Abstract : In practice, thyristor rectifiers are used as high current-low power supplies. Under certain conditions such rectifiers introduce subharmonic resonances. In this paper, a limit cycling voltage regulator system is simulated in the digital computer. The reference voltage and load are varied and the system gain is changed for better understanding of their effects on the subharmonics. A Fourier analysis of the output wave shape then determined the existence and amplitude of subharmonic components. (Author)
