| Abstract |
The output voltage of flyback and forward DC/DC converters can be adjusted by affecting the width of the power switch pulses. Closed-loop control designed to control the average value of the output voltage cannot eliminate the output voltage error produced by the input voltage fluctuations or the load current pulsatlons. In order to suppress the output voltage transients, the pulse width modulator should be placed in the closed loop controlling the output voltage instantaneous value. Modulation signal samples consist of reference signal and samples of the output filter states. With the proper selection of the regulator structure and feedback coefficients, the dead-beat response can be achieved for both flyback and forward converters. The paper presents theoretical background and design considerations for both flyback and forward converters along with the parameter setting guidelines. |
