Abstract :
A small-signal model for a multiple-output forward converter with current model control is derived. The model can accurately predict the small-signal characteristics for current mode control. Both theoretical and experimental results show that the power stage pole-zero relative positions, which are critical to the compensator design, are not affected by introducing current mode control
