Abstract :
This paper presents the modeling and control of the three-phase high power factor PWM-ZVS power supply with a single power stage presented previously by te authors (see Proc. PESC, Taipei, Taiwan, IEEE, p.356-62, 1994). A small signals model of the converter is developed by using the PWM switch equivalent circuit technique. The transfer function which describes the dynamic behavior of the converter is obtained from the model. A complete method to calculate the parameters and coefficients of the developed model, as well as the control systems are presented. Simulations confirm the theoretical results
