Prof. Roberto Perini

Argomenti del programma: 1) The components . Diodes, thyristors and controllable switches; transformers and reactors for the conversion, auxiliary components (inductors, capacitors for power factor correction and filtering). 2) General aspects . Real switches (characteristic curves, losses, delays,…); electrical and energetic quantities (average and RMS values, harmonics, power, efficiency, power factor).

Argomenti del programma: 1) The components . Diodes and controllable switches (characteristic curves, losses, delays, …). Switching and switching losses. 2) Thermal behaviour of the electronic converters . Systems with one or two time constants, thermal transient impedance, cooling. 3) Line-commutated a.c-d.c. conversion . Three – phase diode rectifier, with an RL load; harmonic analysis. 4) D.c. – d.c. conversion.
