Abstract

In this paper, a novel digital control algorithm is proposed to achieve an excellent dynamic performance for two-transistor forward converter. By using the charge balance control(CBC), the optimal transient time and the suitable duty cycle series can be predicted, then better transient performance can be obtained. A comparison of dynamic performances between CBC and conventional voltage mode control is performed in Matlab/Simulink, the results demonstrate the superiority of proposed algorithm.
