Abstract : Some Nonlinear Feedback Control Systems under high gain conditions exhibit the phenomenon of subharmonic instability, or contain subharmonics of the fundamental output frequency. A general discussion of subharmonics in nonlinear systems is followed by an investigation of ripple instability in a forced limit-cycling voltage regulator containing a thyristor or SCR bridge utilizing an ON-OFF switching scheme. A digital computer program is used to simulate the dynamic response of the system under different loading conditions and for different reference voltage levels. (Author)
