A method for the preestimation of the iterative initial value in solving a system of nonlinear transcendental equations is described. It can guarantee the convergerce of a solution and decrase the number of iteratioon cycles. A novel concept, expanded programmed PWM technique, is proposed. The conclusion has important theoretical and practical significance in improving the comprehensive performance index of the generalized active filter (GAF).
