In general, high frequency operation allows the use of small-sized passive components in switch mode power supplies (SMPS), while it causes switching losses to increase in a hard switching mode. To reduce switching losses at high switching frequencies, many soft switching techniques have been developed. Among them, load resonant techniques and zero voltage transition techniques are widely used.

Generating asymmetrical beam patterns approximately ±80° about the horizontal axis and 40° about the vertical, LPRS’ Pro-Wave US040015 ultrasonic sensor meets the requirements of most car reversing aids. The component has 3
Larry Hornbeck holds a series of patents that form the foundation for the digital micromirror device (DMD) — an array of tiny mirrors that create an image by directing pulses of “digital” light through a projection lens and onto a television, presentation, or movie theater screen. Now his work has earned a place in the limelight of the National Inventors Hall of Fame this May. This year, the Hall is recognizing the 50th anniversary of integrated circuit technology by
The HD RooTenna enclosure from Laird is designed to accommodate smaller-sized equipment requirements for broadband wireless access (BWA) suppliers and carriers who deploy industrial WiFi / WLAN / WiMax / LTE systems, mesh networks, Wi-PoP base stations, and/or client antennas using Point-to-Point and WISP applications.
