摘要

A new method is proposed in this paper to distribute the steady-state output voltage errors in a two-output forward converter. The cross regulation between the two output voltages are described in terms of the circuit parameters. An objective function is formed for each of the two outputs to track its reference within the specified error. The legitimate duty cycle range is located through the transfer characteristics between the duty cycle and the load currents. The weighting feedback gains of the two output voltages can be determined by the presented control scheme which optimizes the objective function. The proposed method is suitable for a two-output system without a dominant load. Experiments on a prototype are conducted to show that there exist a duty cycle range and a set of weighted feedback gains minimizing the defined objective function.
