Resum:
Power supply for microprocessor boards is a great challenge, nowadays, in the field of power converters design for VRM. Microprocessors are exigent loads which require high current and low voltage, and also must react very fast to changes in consumption besides a voltage narrow tolerance range. <br/>This thesis analyzes several converters topologies and their controllers which satisfy the VRM requirements. The thesis proposes a new converter topology which has the fastest, among the analyzed topologies, behavior in front of abrupt consumption demand besides a high voltage reduction-ratio. <br/>We derive the design expressions for the DC-DC converter and the controller parameters according to the VRM specifications. The analysis has been corroborated by means of PSIM simulator. Simulation waveforms show a perfect agreement with previous analytical derivation.
