Alpha and Omega Semiconductor Enters the IGBT Market
Alpha and Omega Semiconductor Limited (AOS) announced the release of its first family of high efficiency 600V Insulated Gate Bipolar Transistors (IGBTs) in AlphaIGBT™ technology to address the growing need for energy efficient devices targeting motor control and power conversion applications. AOS's proprietary AlphaIGBT technology combines a unique cell and vertical device structure to offer what the company claims to be the best-in-class conduction (VCE(SAT)) versus switching loss (EOFF) trade-off and longer short-circuit capability. As a result, AlphaIGBT enables a wide operation frequency range to address a variety of applications such as white goods (air conditioners, refrigerators, washing machines), industrial equipment (general inverters, servo motors, sewing machines, welding machines, uninterruptible power supplies), as well as commercial type heating and solar inverters.

AOS's AlphaIGBT products offer 2.5 times lower turn-off switching loss (EOFF) and 2 times higher short circuit withstand time (SCWT) rating compared to the current leading competition device with similar VCE(SAT) values. The ultra low gate-charge (Qg) of AlphaIGBT makes the devices incredibly easy to drive. In addition, the low QGC/QGE ratio allows the devices to withstand higher dV/dt transients and prevents oscillation issues in bridge applications. Combined with the 5.6V VGE(TH), a feature that can be used as an advantage to extend the use of unipolar (0-15V) gate drives saving the expense and complexity of bipolar (-15/15V) gate drives. The positive temperature coefficient of VCE(SAT) and low overall gate charge characteristics of AlphaIGBT technology allow designers to easily parallel more devices and, or larger devices with existing drive circuits.
"After successfully establishing its position in the low-voltage to high-voltage MOSFET markets with best-in-class products, AOS is now ready to open a new chapter by offering superior IGBT products," said Yalcin Bulut, Vice President of Discrete Product Lines at AOS. "With an expertise in device physics and deep system and application knowledge, AOS is raising the bar for IGBT performance as well."

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
