Nondissipative Clamping Benefits DC-DC Converters
Sep 1, 2005
Even if small, a transformer's leakage inductance reduces the efficiency of some isolated dc-dc converter topologies. However, the technique of lossless voltage clamping helps restore most of the lost energy....
Advances in Discrete Semiconductors March On
Sep 1, 2005
The past three decades have heralded the introduction of MOSFETs, IGBTs, silicon, Schottky and silicon-carbide Schottky diodes, as well as continuing advances in high-voltage rectifiers....
Buck Converter Losses Under the Microscope
Feb 1, 2005
The synchronous buck converter is the most popular topology in the PC market. The race between the top MOSFET companies is heating up with the rush to design new devices that are faster and better suited to meet the demands of the microprocessor makers....
Sic Puts New Spin On Motor Drives
Jan 1, 2005
Silicon carbide enables the creation of near perfect
high-voltage diodes whose speed and
power-handling capabilities open new applications
in variable-frequency motor drives. This
will lead to higher density power modules that
operate at higher junction temperatures....
Passive Current Sharing Boosts Power and Reliability
Jan 1, 2005
Passive current sharing is a method of paralleling the outputs of two or more power supplies or dc-dc converters so that they share the load near equally....
Eric Lidow: Lifetime Achievement Award Recipient
Sep 1, 2004
To list the highlights of Eric Lidow's career in power electronics is to chronicle many of this industry's milestones dating back to the introduction...
SiC Schottky Diodes in Power Factor Correction
Aug 1, 2004
Active Power Factor Correction (PFC) is widely used in today's power supplies. Government regulations and customer requirements must be satisfied when...
Hybrid Rectifier Excels in Power ORing Applications
Jun 1, 2004
ORing diodes are a necessary evil of high-reliability systems. They're used to isolate redundant power sources so a failure of one source won't bring...
SiC Schottky Diodes Improve Boost Converter Performance
Mar 1, 2003
SiC Schottky diodes dramatically reduce the importance of switching frequency, making it possible to find a new optimum in boost converter design with simultaneous reduction of the system's size and power loss....
