摘要：
Analytical and experimental considerations of the dynamic characteristics of a voltage controlled buck-type de-to-de converter employing load current feedforward are described. The performance index, integral of the output voltage square error is introduced to evaluate the dynamic behavior of the output voltage by taking a transfer function of a current transformer into consideration. As a result, optimum conditions of the feedforward parameters that give the excellent dynamic regulation are derived. Furthermore, effective control region of the feedforward limited by the saturation characteristics of the PWM is discussed.
