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.
A current-fed regulating converter using a new topology is described. The circuit uses a novel switching scheme to increase the line voltage operating range. The converter circuit is shewn to be one member of a family of circuits, each a little different from the others but sharing common characteristics.
A new multiple-output dc-dc converter is analyzed, in which the cross regulation is performed by the energy-storage reactor as well as the transformer. The steady state and the dynamic characteristics of this converter is compared both theoretically and experimentally with those of the conventional one composed of the step-up-down type circuit. As the results of comparative analysis, it is revealed...
