Abstract :
PWM gain scheduling control is applied to a load-sharing system driven by different line sources whose voltages vary over a wide range. This system can distribute total output current among converter modules with various current ratings. The large-signal behavior of such a system is verified, based primarily on computer simulation. Based on the small-signal analysis, the design procedure for the current and voltage error amplifiers is shown in detail. The system relative stability is investigated to ensure that the performance requirements are satisfied. It is pointed out that the loop-gain function in a multiple-loop system is not as useful as that in a single-loop system. In other words. the current and voltage error amplifiers or compensators need to be selected based on the system characteristic equation, which is uniquely defined for a system
