Abstract: Described is a new partial power converter (PPC) for the DC-DC stage of rapid-charging stations for electric vehicles (EV). The proposed converter manages only a fraction of the total power delivered from the grid to the battery, which increases the general efficiency of the system and the power density while potentially reducing the cost of the charger. The proposed topology is based on a switched capacitor between the AC terminals of a bridge converter H and does not require high-frequency isolation transformers in order to provide a source of controllable voltage between the CC link and the battery. The proposed concept can be implemented by using interposed power cells, which can improve energy quality, reduce the size of the inductor, and allow scalability for chargers of higher nominal power.

Abstract: The present invention proposes a new method for solving the problem of fault tolerance. This new approach obtains all secondary routes assigned to each possible connection (user). The secondary routes replace the main routes when these are affected by at least one fault, which keeps the users connected as long as, for each connection, there is at least one route with operative links for reaching the destination nodes thereof. This new approach solves the general case of an arbitrary set of simultaneous link failures. The method also assesses the number of wavelengths for each link of the network, so that the probability of any connection request from a determined user c being blocked is less than a predefined threshold ?c, despite the possible occurrence of the fault scenario.
