A switched-capacitor programmable filter is proposed as educational tool for the feedback compensation of power converters. The transfer function of the external feedback network, expressed in the Z-transform domain, can be assigned by means of Multiplying DACs. The cancellation of poles and zeros of switching power cells is precisely implemented even in the case they are complex. An ideal final single...
An analog adaptive controller of power converters based upon a switched capacitor programmable filter is described. The transfer function of the external feedback network is continuously updated by the readouts of the input variables. A rough discretization of the inputs is obtained by a small number of fast comparators that digitally program the filter by means of a look-up table. The analog output...
The lasts generations of microprocessors have shown an increase in the operating frequency and, of course, in the supply characteristics. The different need of power requested made necessary new solution for the distributed power supply architectures (DPA) and claimed the use of converters suitable to meet the new high efficiency and high power exigencies. This paper is focused on the design and dynamic...
The exigency of a rapid prototyping of power converters represents an important issue for the power electronics market and pushes the designer toward the search of software tools able to depict the static and dynamic behavior of the electrical circuits. The availability of reliable analysis tools open the possibility to their use not only for the design but also for the test of the converters in circumstances...
