Simple Digital Control Improving Dynamic Performance of Power Factor Preregulators - Power Electronics, IEEE Transactions on

This paper presents the practical implementation of a fully digital control for boost power factor preregulators (PFP’s). The control algorithm, which is simple and fast, provides a significant improvement in the system’s dynamic performance compared to usual analog control techniques. The paper discusses the design criteria and the actions taken for the implementation of the digital control, w...

A line-frequency-commutated rectifier complying with IEC 1000-3-2 standard

Consumer and household appliances require low-cost ac/dc power supplies complying with EMC standards. The commonly employed passive solutions are bulky and do not provide output voltage stabilization. Active solutions, based on power-factor correctors with high-frequency switching, provide compactness and regulation capability, but are generally expensive due to the need for fast-recovery diode...

Verilog-A behavioral modeling of power converters

The paper presents the implementation of a Verilog-A based, behavioral macro model for a flyback power converter to be used in a Spice based simulator (SpectreS by Cadence©). The paper discusses the effectiveness of this simulation strategy in reducing the complexity of a simulation problem, namely the analysis of a new smart-power integrated circuit (IC). The IC consists in a flyback PFC contr...

Susceptibility of Integrated Circuits to RFI

This paper surveys the results of an extended research activity concerning the effects of radio frequency interference (RFI) on integrated circuits (IC's). Initially, the possible injection methods for conducted and radiated interference are presented, discussing their applicability and limitations. Then, the basic results of the susceptibility analysis of operational amplifiers and smart power...
