1.- To study the nowadays solutions for high power and high output voltage converters, and compare them with the performances of the PRC-LCC resonant converter with a capacitor as output filter.

2.- To obtain a dynamical model for the PRC-LCC resonant converter with capacitor as output filter. This model will be formulated in its large signal appearance, and experimentally verified.

3.- To deduce from the large signal model a new and more simple steady state solution.

4.- To approximate the large signal model for a lineal one, obtaining, this way, a small signal model for the topology.

5.- To particularise the three previous models for the optimum switching area defined in the objective 1.

6.- To look deeply into the study of high voltage transformers, providing a guide for its design.

The main goal is to derive a new topology design for AC/DC HV converters in a wide output power operation range.

The thesis defines a multilevel topology as a solution to operate in the aforementioned conditions, with reasonable resonant current values at low power.

The parasitic transformer components are included in the topology, and they are used as an extra elements that help to reduce the output power level.

Experimental results are provided.
