The hype that accompanied the introduction of the early digital power controller ICs and the debates over the merits of digital power control have faded as the technology has gained acceptance in the marketplace. But that does not mean there aren’t still issues to be settled in this area, particularly those concerning how best to apply digital power control. In his article, Peter Markowski argues that power supply designers should begin looking beyond microcontrollers, DSPs, and ASICs as their platforms for implementing digital control and consider the advantages of using programmable logic devices such as FPGAs. As Peter explains, advances in these devices and in their design tools have made FPGAs better suited to power converter designs and more friendly to designers. Some power supply engineers may be surprised to learn that new FPGA technology has essentially rewritten the tradeoffs in performance versus design time when comparing FPGAs with DSPs and ASICs in digital power applications. This issue also brings you the third and final installment in Christophe Basso’s series on the active-clamp forward converter in which Christophe presents the final steps in the derivation of the control-to-output transfer function. Meanwhile, Michael Hopkins describes a novel technology for reducing the power consumption of digital circuits. Additionally, this issue brings you an update on new magnetic components, a preview of the International Symposium on Power Semiconductor Devices and ICs, and more.
