An accurate impulse model is presented, for the purpose of analyzing the P.W.M. chopper system whose pulse-width is determined by comparing the control voltage with a triangular reference voltage. For natural sampling system, existence of three different operating modes and dead-zone are clarified. Approximate dead-beat gain and critical gain are presented.
