| Abstract |
A dc/dc converter is used in some ac traction drive to hold the input voltage of the inverter to the prefixed value. A dc/dc converter is realized by inserting a conventional chopper circuitry between two power filters, the first one connected to the contact line, the second one to the inverter. The dynamic behaviour of the chopper is highly influenced by these filters. The control of the inverter voltage is effected by applying a PWM technique. In this paper the procedure for designing the control strategy is illustrated. This paper deals with a step-up converter. The general model is firstly deduced and the static characteristics are presented. Subsequently, the linearized model is deduced: The control strategy is worked out so as to satisfy different requirements in the input-output and in the disturbance-output behaviour. |
