Linear supply uses switch-mode regulation - 19-Jul-01 Issue of EDN You
can use simple circuits to implement small, regulated plug-in power supplies. In
Figure 1, a basic and versatile 5V supply uses a zener diode and an emitter-follower
transistor. You must calculate and design the transformer such that Q1 is close to
saturation at low mains voltages and nominal output current.... [Design Idea by David

Method provides self timing for synchronous rectifiers - 16-May-02 Issue of
EDN Synchronous rectifiers are MOSFETs, driven in such a way as to perform a
rectifying function. They often take the place of diodes in the output-rectification
stage of switching power converters, because of their lower on-state power loss. In
power circuits, synchronous rectifiers are often complicated to use because of timing
issues.... [Design Idea by Giampaolo Carli, SAE Power Co, Saint-Lazare, Quebec, PQ,

RC network quashes auxiliary winding in quasiresonant converter - 1-Apr-04
Issue of EDN Quasi-square-wave-resonant converters, also known as QR
(quasiresonant] converters, allow the design of flyback-type SMPSs (switch-mode power
supplies] with a reduced EMI (electromagnetic-interference] signature and improved
efficiency. You can achieve so-called QR operation by authorizing the turn-on of the
switching MOSFET when the drain voltage reaches its minimum—hence, the name valle....

Reduce EMI by sweeping a power supply's frequency - 27-May-04 Issue of EDN
Switching power supplies can be notorious noise generators. You should prevent this
noise, which is conducted, radiated, or both, from returning to the input source,
where it can potentially wreak havoc on other devices operating from the same input
power. The goal of an EMI (electromagnetic-interference] filter is to block this noise
and provide a low-impedance path back to the noise source.... [Design Idea by John
